Bismillahir Rahmanir Rahim Assalamu Alaikum, dear brothers, sisters and friends. Known as the book written by Muhammad Saleh Al-Munajjid, "Following the Instinct to Destroy the Heart." In this book in the series "Faith Destroyer: Following Instinct", the respected author discusses the definition of instinct, the disadvantages of instinct and the advantages of not following instinct, the reasons for following instinct, the remedy for following instinct and the explanation of praiseworthy and reprehensible instinct. 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.
