আল্লাহর দিকে দাওয়াতের সম্বল বই

Bismillahir Rahmanir RahimAssalamu Alaikum, dear brothers, sisters and friends. One of the best scholars of the age, Allama Sheikh Muhammad Ibn Saleh Al-Othaimeen, is known as the author of the book "Content for Calling to Allah". All the pages of this book are highlighted in this app. I published the whole book for free for those Muslim brothers who could not afford it.Hope you will encourage us with your valuable comments and ratings.
