Bismillahir Rahmanir Rahim Assalamu Alaikum, dear brothers, sisters and friends. The famous book of Aqeedah of the four Imams is known as "Salah Ibn Muhammad Al-Budair". This is a short booklet. It summarizes the issues of Tauhid, the principles of the religion and its related matters, which every Muslim must know and believe. And these have been collected from the books on the beliefs of the four Imams. They are Imam Abu Hanifa, Imam Malik, Imam Shafi'i, Imam Ahmad Ibn Hamble and their followers. May Allah have mercy on them all. They all agreed with the creed of Ahl as-Sunnah wal Jama'at and did not disagree. 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.
