Introduction

Ash-Shifa bi Ta'rif Huquq al-Mustafa (The Cure by the Recognition of the Rights of the Chosen One) is among the most celebrated and beloved books ever written in the Islamic tradition. Its author, Qadi Abu al-Fadl Iyad ibn Musa al-Yahsubi (476–544 AH / 1083–1149 CE), was the supreme judge (qadi) of Ceuta and Granada, a master hadith scholar of the Maliki school, and one of the towering intellectual figures of Andalusian and North African Islam. Born in Ceuta, he studied under scores of scholars across the Maghrib and Andalus and became the foremost authority of his age on hadith and the biography of the Prophet ﷺ.

The Shifa was composed as a comprehensive treatment of everything the Muslim owes to the Prophet Muhammad ﷺ in terms of knowledge, love, reverence, and obedience. Qadi Iyad organized it into two main parts: the first details the honors, qualities, and rights that Allah has bestowed upon the Prophet ﷺ — his noble character, his physical description, his miracles, his rank before Allah — while the second part addresses the obligations of the believer toward the Prophet ﷺ, including the legal consequences of disrespect or denial of his prophethood. Together, the two parts form an exhaustive legal and theological treatise on prophetic reverence.

Few books in Islamic history have achieved the level of veneration accorded to the Shifa. Across the Arab world, the Indian subcontinent, West Africa, Southeast Asia, and the Ottoman lands, it has been taught in mosque circles, memorized in full by devoted students, placed in homes as a source of blessing, and recited at times of difficulty or illness — giving it the reputation of a healing text, consistent with its title. Dozens of scholars wrote commentaries on it, and it remains a staple of traditional Islamic education to this day.

From the perspective of Ahl us-Sunnah wal-Jama'ah, the Shifa is a masterwork of Sunni theology and jurisprudence. Qadi Iyad grounds his discussions firmly in Quran, sound hadith, and the consensus of scholars, making it a reliable source for understanding the doctrinal and legal dimensions of prophetic love. Students of the Maliki school will find it particularly rich, though its appeal transcends any single legal tradition. Its breadth of hadith citation and precise theological formulations make it essential reading for any serious student of prophetic biography and Islamic theology.

Readers should note that the Shifa is a work of advanced Islamic scholarship — not a simple devotional text. Qadi Iyad engages with complex jurisprudential discussions, including rulings on apostasy and blasphemy that require careful contextual reading. The book rewards patient, guided study with a qualified teacher. Those approaching it for the first time should focus on the first part, which is universally accessible and spiritually enriching, before engaging the more technical jurisprudential discussions of the second part.
