The versatile genius of Imam Ja’far as-Sadiq in all branches of knowledge was acclaimed throughout the Islamic world, which attracted students from far-off places towards him till the strength of his disciples had reached four thousand. The scholars and experts in Divine Law have quoted many ahadith (traditions) from Imam Ja’far as-Sadiq. His disciples compiled hundred of books on various branches of science and arts. Other than fiqh (Islamic jurisprudence), hadith (tradition), tafsir (exegesis of the Holy Qur’an), etc., the Holy Imam also imparted mathematics and chemistry to some of his disciples. Jabir ibn Hayyan at-Tusi, a famous scholar of mathematics, was one of the Imam’s disciples who benefited from the Imam’s knowledge and guidance and was able to write four hundred books on different subjects. It is an undeniable historical truth that all the great scholars of Islam were indebted for their learning to the very presence of the Ahlu’l-bayt who were the fountain of knowledge and learning for all.
