The famous 6th century Hijra classical text Ash-Shifa is widely accepted as the best, most comprehensive and most important book about the Messenger of Allah, may Allah bless him and grant him peace. Its full Arabic title is Ash-Shifa' bi-ta'rif huquq Mustafa ("Healing by the Recognition of the Rights of the Chosen One"). Qadi Iyad writes in the Introduction: "You have repeatedly asked me to write something which gathers together all that is necessary to acquaint the reader with the true stature of the Prophet, peace and blessings be upon him, with the esteem and respect which is due to him, and with the verdict regarding anyone who does not fulfill what his stature demands or who attempts to denigrate his supreme status - even by as much as a nail-paring. I have been asked to compile what our forebears and Imams have said on this subject and I will amplify it with ayats from the Qur'an and other examples." This masterly translation by Aisha Bewley has become almost as well known as the Arabic original in modern times, and has served a whole generation of English-speaking Muslims as their means of acquiring knowledge of the Prophet Muhammad, may Allah bless him and grant him peace.
