During this segment of the ‘Abbaasid rule, a format for writing Fiqh books evolved. This format became a standard, which has remained in practice until today. The various issues were grouped under main headings and the main headings under chapters, each of which represented a major topic from Sharee’ah. Even thr door of the chapters became standardised. The authors would begin with the four pillars after Eemaan (faith), since Eemaan was dealt with in books of Islamic theology. After treating the laws and issues concerning Tahaarah (hygiene) and Salaah (prayer), Sawm (fasting), Zakaah (poor tax) and Hajj (pilgrimage), they would proceed on to Nikaah (marriage) and Talaaq (divorce), then Bay’ (business transactions) and then Aadaab (etiquette). In dealing with any of these issues, and author from any one Madh-hab would mention the different proofs used by all of the Madh-hab’s position, while refuting the arguments of the other Madh-habs.
