I would like to ask about the book Ar-Raheequl Makhtum (The Sealed Nectar) by Safiur-Rahman Al-Mubarakpuri. Should we study the Seerah of Prophet Muhammad, peace be upon him, from this book? If not, could you mention which books we should study the seerah from? May Allah bless you.
Yes. You can study seerah from this book but just notice that there are several weak hadeeth in it. Also, there is an English translation for Imam Ibn Al Qayyim’s book: Provisions for the Hereafter.
