Dalailul Khoirat is a book compiled by Imam Abu Abdulloh Muhammad bin Sulaiman Al Jazuli, also known as Syeh Jazuli. The book consists of sholawat, a form of Islamic prayer, and the author vowed to compile it after a miraculous incident where he was helped by someone who had been reading sholawat. After 41 years of spiritual seclusion and contemplation, Syeh Jazuli was able to compile the book. The book has gained a lot of popularity and is widely read by many people who visit his tomb in Marakisi, Africa. The book is a testament to the power of faith and prayer and is a valuable resource for those seeking spiritual enlightenment.
