Imam Jalal al-Din Suyuti (d. 911/1505) was one of the most prolific writers produced by the Islamic world. He is the author of over 700 works in virtually every field known to Islamic science, including the famous Jalalayn commentary of the Qur’an (of which he was co-author). His works are still widely used, and his name is a by-word for breadth of learning, voluminous output and a saintly life. The Work of Day and Night is Imam Suyuti’s collection of the daily and nightly practices of the Prophet of Islam and includes instructions on how to follow the Prophet in everyday actions and supplications. In it the reader will find: the prayers said upon awakening, before eating and when dressing; the acts carried out at various times of the day, and between prayers; the supplications recited in times of distress as well as of intimacy with God; and much else. This book is invaluable for learning the practices of the Prophet and integrating it into one’s life.
