Bismillahir Rahmanir RahimAssalamu Alaikum, dear brothers, sisters and friends. "Ikhlas, why and how" is famous as the book written by Abdullah Shaheed Abdur Rahman. Why and how sincerity: Sincerity is an important factor in performing Ibadat. Worship without sincerity is not acceptable to Allah. Sincerity happens suddenly - its not a matter of going. Sincerity is achieved as a result of constant pursuit of living in the path of Allah. The definition of sincerity and the way and means of acquiring sincerity have been discussed in detail in the book. 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.Hopefully you will encourage us with your valuable comments and ratings.
