The book is a translation of a valuable book regarding a precious hadith of the Messenger (p.b.u.h.). The subject of the hadith is about the angels of the highest heaven disputing about deeds, which expiate sin and raise the level in the Hereafter. Al-hafidh Ibn Rajab has very beautifully the hadith in detail. We realise that the book will help Muslims to do more good deeds as it is an encouragement and full of reminders with quotes from the Qur'an and ahadith.
