"This is the Fat'h al-Basaa'ir of Shehu Uthman ibn Fuduye` in which he lays plain the entire gamut of knowledge, who has it, who almost has it and who doesnt and how to recognize all of them. He delineates in this the text an explanation of the three divisions of the religion: Imaan, Islam and Ihsaan, what parts of these are among the individual obligations and those that are among the collective obligations . What is important is that the Shehu explains in the final chapter of the text the basis of the disagreement of the mujtahid imams and how thier differences are all sound and are paths which leade to Paradise."
