Shiavault - a Vault of Shia Islamic Books The Basics of Islamic Jurisprudence The Jurisprudential Sects of Islam We learned that Islamic jurisprudence is the knowledge of Islamic laws, what is permissible and what is forbidden, what is obligatory, what is disliked (not recommended, unfavorable) and what is recommended (favorable), and what is correct and what is incorrect. We also know that these Islamic laws are derived from the Qurān and prophetic traditions.
We also know that the Muslims in the time of the Prophet (s) would take their religious rulings from him. They would take the rulings that had to do with worship, like prayer, pilgrimage, fasting and spiritual purification, or the rulings that had to do transactions like trade, partnership, rent, land, marriage and divorce and other rules that are found in the religion from him.
Then, after his death, some situations arose in one's prayer, fast, life, business, partnership or pilgrimage…etc that did not occur during the Prophet's (s) lifetime. They needed to know what the religious ruling was. In this case they would refer to some of the companions to take the ruling from them. Some took rulings from Imām ‛Alī bin Abī Tālib (a), some from ‛Abd Allah bin ‛Abbās and some from ‛Abd Allah bin Mas‛ūd.
‛Alī (a) was the most knowledgeable companion; the Prophet (s) said the following about him: “I am the city of knowledge and ‛Alī is its entrance.”[^1] But, we see some different verdicts passed by different companions and the generation that came after them called the tābi‛īn . There were many mujtahids and many differences in verdicts, but there were no jurisprudential sects like there are today.
The Muslims would refer to the scholars amongst the companions, tābi‛īn and Imāms (a) for the religious rulings that they needed. Imām ‛Alī bin al-Hussayn al-Sajjād (a), Imām Muhammad bin ‛Alī al-Bāqir (a) and Imām Ja‛far bin Muhammad al-Sādiq (a) lived in these times. How Jurisprudence sects were formed and when The divisions of Muslims became widespread after the murder of the third khalīfa , ‛Uthmān bin ‛Affān.
At that time the Muslims swore allegiance to Imām ‛Alī bin Abī Tālib (a) but Mu‛āwīyah bin Abī Sufyān refused to swear allegiance to him. Nobody followed him in this except the people of Syria. He formed his own, autonomous government there. He also took some jurists and some people who related traditions with him, and thus the major division was started.
