Muhammad was the son of Abdullah, whose ancestry reached the Prophet Ismael son of the Prophet Abraham, peace be upon them. The Prophet Muhammad was born in the city of Mecca, in Arabia, on a Friday, the 17th day of the lunar month of Rabi-I, in the year 570 CE into a noble family whose fathers and ancestors were amongst the chiefs of the Quraysh tribe, and the Bani-Hashim clan.Muhammad grew up to become a fine young man. He became known for his excellent manners, and because of the honesty in his conduct and dealings, he was referred to as al-Amin (The Trustworthy One).
Jafar b. Muḥammad b. Alī b. al-Husayn known as Imam al-Sadiq (PBUH) is the sixth Imam of Imamiyya. His Imamate lasted 34 (lunar) years and was concurrent with the reign of the last five Umayyad caliphs and with that of the first two Abbasid caliphs, al-Saffah and al-Mansur al-Dawaniqi. Because of the weakness of the Umayyad rule at his time, Imam al-Sadiq was able to have relatively wider scholarly activities. His companions, students, and those who quoted hadiths from him are said to have amounted to four thousand people. Most of the hadiths of Ahl al-Bayt recorded in Shiite hadith collections are from Imam al-Sadiq.
