Book name is “Salaat! Is your’s Correct? Punctuality and correct performance of Salaat “Written by Maulana Fazlur Rahman Azmi. After Imaan, Salaat is the most important principle of Islam. It is thus quite understandable why the Shariat has so much emphasized the importance of its correct performance, punctuality with regard to it, etc. It must be clearly understood that Salaat will only be accepted if it is done in the Sunnah. Even a slight deviation from this negates the value of Salaat. Furthermore the foundation for the success of the believers has been placed on Salaat. Those believers who are neglectful or do not perform their Salaat correctly have been warned of annihilation and destruction.
Allah Ta’ala says in the Quraan:
Safeguard your Salaat and (especially) the middle Salaat (i.e. Asr Salaat) and stand before Allah with humility.
