Daga nan ya koma yin nazarin fiqhun Shafi'iyya, sai ya bar shi. Daga baya kuma ya koma yin nazarin mazhabar Abu Dawud Az-Zahiri daga wajen Mas'ood bin Sulayman.

Ibn Hazm (384 AH - 456 AH) was born in Cordoba in Andalusia (Spain), which at that time was the capital of science for all of Europe. He studied Qur‟an, Hadith, and Maliki Fiqh. He then moved to study Shafi‟i‟ Fiqh, and left it. Later on, he moved to study about the Madhab of Abu Dawud Az-Zahiri from Mas‟ood bin Sulayman.

Ibn Hazm ya ƙi Qiyas, kuma ya riƙe ma'anar zahirin nassi kawai, har ya kai ga cewa idan mutum ya yi fitsari a cikin ruwa, misali, zai ɗauki ruwan a matsayin najasa; amma idan fitsarin na alade ne, to ruwan ba zai zama najasa ba. Ibn Hazm ya yi yaƙi da Taqleed, kuma ya yi kira ga mutane su tattauna al'amura bisa Daleel. Wannan ya jawo masa wasu matsaloli daga wasu mutane a wancan lokaci. Littafinsa mafi muhimmanci shi ne Al-Muhalla.

Ibn Hazm rejected Qiyas and took only the literal meaning of the text to the point that if a man urinated in a body of water; for example, he would consider for the water Najis (filthy); however, if the urine were from a pig, then the water would not be considered as najis. Ibn Hazm fought against Taqleed and called the people to discuss issues based on the Daleel. This caused him some problems from some people at that time. His most important book is Al-Muhalla.
