Bismillahir Rahmanir Rahim Assalamu Alaikum, dear brothers, sisters and friends. Zak's Ullah Abul Khair's book "Jum'ar Din Bidhan" is famous. This is an important book about the rules of Jumu'ah. The book briefly discusses the virtues of Jumu'ah, the virtues of Jumu'ah prayer, the do's and don'ts of Jumu'ah, the rules and etiquettes of Jum'ah prayer in the light of Qur'an and Sunnah. 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.
