A valuable manuscript written on 266 pages by Imam 'Abd al-'Az-iz b. 'All b. al-'Izz al-Baghdad7i al-Bakr-i al-Uanball al-Maqdis! (770-846 AH / 1369-1443 CE) Chief Justice of Holy Jerusalem. The original manuscript is available at the Arab Academy of Knowledge, Damascus and a copy at Jum'ah Al-Majid Centre for Culture and Heritage, Dubai. The author gathered all verses of patience and trust in Allah and explained them. He derived evidence from the Prophet's tradition, companions, and successors. He cited incidents of the Prophet's biography underlining the value of patience and trust in Allah as an ethical tenet which all heavenly doctrines preach and which the magnanimous Islamic doctrine has adopted as a basic principle of its mission. The book could be classified as an objective exegesis and represents a comprehensive and unprecedented study. This research is divided into two sections: Study and Revision. The study contains an introduction, two chapters, and a conclusion. In the introduction I discuss the subject's importance, selection motive, objectives, former studies, and difficulties encountered. The first chapter is specified for the author's biography: His time and life. The second chapter contains the description, study, and manuscript criticism; divided into two topics: Study of the book and my work in the revision. The conclusion sums up the results, proposals, and recommendations. Selected samples of manuscript sheets are appended. The revision section was accurately completed using an objective scholarly method to regulate the text, supply punctuation marks, number pages, rewrite text in accordance with modem rules of dictation, locate suras and verses, refer Had-iths to their sources, explain vague utterances, conform Qur'anic texts to Uthmani scripture, define idioms, verify jurisprudence issues, correct grammatical mistakes, and describe eminent persons and places.
