Bismillahir Rahmanir Rahim Assalamu Alaikum, dear brothers, sisters and friends. "Big Shirk and Small Shirk" is famous as the book written by Mostafizur Rahman bin Abdul Aziz Al-Madani. If a person dies, no matter how many sins he has committed, if he has never associated anyone with Allah, or if he has associated anyone with Him, then he has sincerely repented of it and believed in Him without any shirk, and then he has died. Allah will forgive all his sins by His grace. All the pages of this book are highlighted in this app. I published the whole book for free for the Muslim brothers who could not afford it. Hope you will encourage us with your valuable comments and ratings.
