The book Reforming Mosques from Heresies and Customs was written by Muhammad Jamal al-Qasimi, who believed that the most important duty is to inform people about the heresies and denials that have affected them, because the custodian is responsible for reforming those with him, and in the hadith: “Each of you is a shepherd and each of you is responsible for his flock,“ so seek help from Allah in starting the process and rely on Him in completing this topic and writing this book.
