The fatwa of Mahmud Shaltut was published (in 1959) under the title "Islam: the religion of unity." It was introduced by two arguments. The historical argument about mutual respect and tolerance between different legal schools of Sunnis as well as the Shi'i school. The other was an argument about the harmful effects of prejudice between Muslim schools of fiqh. It was argued that the spirit of ijtihad had turned into antagonism and they were no longer having discussions. Shaltut feels that all schools of fiqh should be ready to accept from one another. They should accept any idea which follows Islamic principles and that ensures the welfare of family and society. As a first step the Ja'fari school of fiqh was included in the curriculum of al-'Azhar.
