Imam Al-Sadiq (a.s.) adopted Taqiyyah as a defensive tool against the violence and threats that were directed against him and the Shiites. Taqiyya was a form of religious dissimulation, or a legal dispensation whereby a believing individual can deny their faith while they are in fear or at risk of significant persecution. In other words, Taqiyya says that it is acceptable to hide one’s true opinions if by revealing them, one puts oneself or others in danger. The doctrine was developed by Imam al-Sadiq(a.s.), and served to protect the Shiites when Al-Mansur, the Abbasid caliph, conducted a brutal and oppressive campaign against Alids and their supporters. According to Moezzi, in the early sources, Taqiyya means “the keeping or safeguarding of the secrets of the Imams’ teaching.” “Divergence of traditions” is, therefore, sometimes justified by Shiite imams as a result of the need for using Taqiyya. “He who is certain that we [the imams] proclaim only the truth (Al-Haqq), may he be satisfied with our teaching,” asserts Imam al-Sadiq (a.s.); “and if he hears us say something contradictory to what he heard earlier, he should know that we are acting only in his own interest.” Practicing Taqiyya also had an esoteric significance for those who believed that their teachings should not be comprehensible to ordinary Ulama (scholars), and so hid their more profound teachings.


According to Haywood, half a dozen religious works bear Imam al-Sadiq’s (a.s.) name as an author, though none of them can be firmly described as being written by Imam al-Ṣadiq (a.s.). It is probable that Imam al-Sadiq (a.s.) was an author who left the writing to his students. Imam Ja’far Al-Sadiq (a.s.) is also cited in a wide range of historical sources, including al-Tabarial-Yaqubi and Al-MasudiAl-Dhahabi recognizes his contribution to Sunni tradition and Isma’ili scholars such as Qadi al-Nu’man[  recorded his traditions in their work.

Ketāb al-jafr is a commentary on the Holy Qur’an which, according to Ibn Khaldun, was first written on the skin of a young bull, which allowed Imam al-Sadiq (a.s.) to reveal the hidden meaning of the Qur’an. Various versions of his will, and a number of collections of legal dicta, are attributed to him as well. There are many reports attributed to him in the early Shiite Hadith collections such as Muhammad ibn Ya’qub al-Kulayni‘s Kitab al-Kafi, where they are featured as central sources of Imami doctrine. “Al-haft wa’l-aẓella” and “Ketāb al-ṣerāṭ” which are containing “secret revelations” to Mofażżal are also attributed to Imam al-Sadiq (a.s.), and had an important role in the elaboration of the esoteric doctrine of the Nosayris, for whom Imam al-Ṣadiq (a.s.) is an influential figure.


Imam Ja’far al-Sadiq presented numerous scientific discoveries, a few of which are described below:

Imam Ja’far al-Sadiq (a.s.) besides being a religious leader, was a scientist, a philosopher, and a dedicated teacher.  He used to teach Theology, Philosophy, Science, and Literature. He was the first scholar in the world who separated science from Philosophy. .

Imam Ja’far al-Sadiq (a.s.) had attacked the theories of famous world philosophers and scientists like Aristotle, Ptolemy, Euclid, and Lavoisier when he was a student in the Academy of his father, Imam Mohammad al-Baqar (a.s.) who died in 114 Hijra.  At that time, there were no scientific, mathematical, or philosophical books or research papers available in Madina for anyone to study or review.

Aristotle was a great thinker and a philosopher. His books Arganan and Physics, are the most precious literary treasures of mankind. His theory that earth was stationary and the sun and stars rotated around it, was widely supported by Ptolemy, the Egyptian Geographer and Astronomer. In the year 94 Hijra, when a model of the then assumed solar system was brought from Egypt to Madina, Imam Ja’far al-Sadiq (a.s.), at that time a 11 year old boy, openly criticized and rejected that Theory. While rejecting the theory of rotation of sun, moon and planets around the earth, Imam Sadiq (a.s.) said that:

“When the sun, during its rotation around earth, passes through 12 Constellations in one year, and remains in each constellation for 30 days, why does it disappear from the sight during night time? It should remain visible from the earth during day time as well as night time.”  This was a very strong objection by a boy of 11 years of age”.

At the age of 12, Imam Sadiq (a.s.) also rejected the Theory of Four Elements of Aristotle and proved it to be totally wrong. Criticizing the theory, he said:

            “I wonder how a man like Aristotle could say that in the world there are only four elements Earth, Water, Fire, and Air. The Earth is not an element. It contains many metals which are elements.  He said Water, Fire and Air were also not elements”.

Imam Ja’far Sadiq (a.s.) was the first person to discover that one of the elements contained by air produces acidity which helps combustion. Without the presence of this material, a combustible material will not burn. He also said this element is essential for breathing and that it supports human life. This was also an important discovery.  Later on the future scientists confirmed the discovery and named this element as Oxygen..

Imam Ja’far as-Sadiq (a.s.) described another important theory. This discovery is about the origin of the Universe. He said :

The Universe was created out of a tiny particle, which had two opposite poles, one with negative charge and other with positive charge. That particle produced Atom. In this way matter came into being. Then the matter diversified. The diversification was caused by density or rarity of the Atoms”.

In the 2nd century of the Hijra it was only in the Muslim countries that the people had the freedom to say and write freely about the heavenly bodies. That is why, Imam Jafar as-Sadiq (a.s.) could discuss his new theories about the sun, moon and stars. At that time the scientists who had discovered the Laws of Planetary Motion had failed to discover as to what causes day and night phenomena. It is therefore highly surprising that Imam Jafar as-Sadiq (a.s.) who lived in Madina, which was not a center of knowledge and learning, made an important discovery in the field of Astronomy. He clearly stated that the earth rotates on its own orbit, completing one full orbit in one day, thus creating day and night. He said one half of the earth that faces the sun creates the day and the other half not facing the sun creates the night..

As regards the shining stars in the Universe, Imam Ja’far as-Sadiq (a.s.) said:

 “Each star is a small universe within the great universe. It is a collection of heavenly bodies like a sun and its satellite. They are all in perpetual motion so that they may not fall down and breakup. If their movement stops, the universe will come to an end. The perpetual motion supports life. It is by the Will of Allah that the eternal motion never stops and life cycle continues.”  He further clarified that there are a few stars that are bigger than the sun and a lot brighter than the sun.

Imam Ja’far as-Sadiq (a.s.) also taught his students the science of medicine. His research and his theories had great impact on science of medicine. During the second and third centuries of Hijra most of the physicians in the Middle East followed the methods of diagnosis and treatment prescribed by him.

 In cases where condition of a patient was such that physician could not determine whether the patient is alive or dead, Imam Ja’far as-Sadiq had suggested that a small incision should be made in his body, specially between his two fingers. If blood comes out, it was a sign that he was alive. There is an historical evidence that his theory was put to test and was found correct.

In addition to his vast knowledge of other subjects, Imam Ja’far as-Sadiq (a.s.) was well versed in the History of Christianity. He knew the origin of the Orthodox and Catholic Churches and the main cause of differences among Christians and their division into many sects. He did not want the divisive element to enter into Shia Theology, and diivide Shias like Christians. It was for that reason that he emphasized Shi’a unity stating that the Holy Prophet (pbuh), and the divinely appointed Leaders (Imams), possessed the divine knowledge relevant to the Universe and all other creations.

In the Eleventh century, Catholic Church was deadly against Astronomy, Philosophy, and other Sciences, and did not preserve any books written by the Philosophers of Greece, Rome and Alexandria. The Greek Philosophers would have been burnt alive if they dared to write about any of the sciences. Whatever ancient books and literature that were available, Muslims translated them in Arabic and preserved them in their libraries. Accordingly, Muslims became the real source of civilization in Europe. About nine hundred years ago, a majority of the Europeans were uneducated,  lived uncivilized life, and had no noble quality and character. Due to ignorance and illiteracy, there was not a single library in Europe. It was their contact with Muslims that changed their life style and became civilized. Muslims had big libraries and many large centers of knowledge and learning. It was Islamic civilization and culture that influenced European life and its culture. In the year 1130 A.D. a Translation Bureau was established in Italy where all books of famous Muslim writers were translated and preserved. These translations opened the eyes of Europeans, and opened a new gate to conduct scientific and philosophical research again in Europe. .

Imam Ja’far al-Sadiq (a.s.) had attacked the theories of famous philosophers Aristotle and Ptolemy when he was a student in the Academy of his father, Imam Mohammad al-Baqar (a.s.), who died in 114 Hijra. At that time there were no scientific, mathematical, or philosophical books or research papers. Accordingly Imam Jafar as-Sadiq (a.s.) knew that Muslim world would be flooded with books of  the philosophers of Greece and Alexandria and that Muslims would blindly accept everything as Gospel truth. Thus, many of their false and fallacious theories would catch their imagination, corrupt their minds, and keep them under total darkness for centuries, which actually did happen. For example, the theory of Aristotle and Ptolemy that earth was center of the Universe and that the sun and stars rotated around it, was generally accepted by the Muslims as correct. Therefore, Imam Mohammad al-Baqar (a.s.) and after his death Imam Ja’far as-Sadiq (a.s.) explained the correct theories of Universe and other creations to their students, and advised them  to spread their teachings and  the correct theories as presented by the two leaders, among other Muslims, and their generations. 

Marveling at the creation of Allah The Almighty, Imam Ja’far as-Sadiq (a.s.) remarked:

            Allah, by His Knowledge and Power, created every living being and endowed each one of them with special power and instinct so that it may succeed in its struggle for survival. How wonderful are his creations. He created animals which can survive in severe cold weather of the frigid regions of the Poles and He created animals, which can live, prosper and propagate in the scorching heat of the tropics and sandy deserts. Many animals, which live in very cold region, sleep during long winters without eating and drinking, and also without having any adverse effect on their health. The hearts of these animals beat 5,000 times per hour when they are awake, and about  60 or 70 times while they sleep during winter. As regards the animals which live in deserts, like camels,  can survive for several days in deserts without water.  Allah gave special power to camels by which they can sense availability of water in deserts from a significant distance. “

Shi’as believe Ja’far al-Sadiq (a.s.) was one of the divinely appointed Imam who had unlimited knowledge of all creations. Whatever theories and research he put forward about Astronomy, Chemistry, Physics, Mathematics, and Medicines was through his divine knowledge. Every physician and scholar who reads his theories will realize and acknowledge that Imam Ja’far as-Sadiq (a.s.) was a genius and fully capable of making important discoveries using his great intellectual power. 

Imam Ja’far as-Sadiq (a.s.) has to his credit a number of maxims, sayings, and short quotations. Many of them have spread throughout the world. His following Maxim gained great popularity:

            ‘When someone is in pain, he thinks of himself”.

This maxim is so correct that it gradually spread all over the world. This maxim is so precise, true and exact that a Canadian scholar considered it as a Law of Psychology, and said that when we have some pain in our body we cannot forget ourselves, however, when we have no pain, mental or physical, we tend to forget ourselves.


Imam Ja’far as-Sadiq (a.s.) married Fatimah binte Al-Hasan, a descendent of of his ancestor Al-Hasan ibne Imam Ali (a.s.), with whom he had two sons, Isma’il and Abdullah al-Aftah. Following  Fatimah’s death, Imam as -Sadiq purchased a Barbery slave named Hamidah Khatun.  He freed her, trained her Islamic values and traditions, and then married her. She borne him two more sons, Musa al-Kadhim (the 7th Twelver Imam) and Muhammad al-Dubaj. Hamidah Khatun was revered by Shias especially by women, for her wisdom. She was known as Hamidah the Pure. Imam as-Sadiq (a.s.) had six other children namely, Ishaq, Ali al-Uraidhi, Al-Abbas, Fatimah, Umm Farwah, and Asmaa.
