This app is on the challenge and response to the so called new salafis who claim that the tarawi prayers during the Ramadan is only 8 rakah while it is an established fact since the time of salfe saleheen that the sahabas and their followers used to pray 20 rakah which is being practised all over the world, even in the land of wahhabism, Mecca and Madina.
So, everyone should have this book to defend the false demands by so called salafis.
