The eminent Muslim scholar and renowned Da`iyah, Sheikh `Abdel Khaliq Hasan Ash-Shareef, states: “No one knows whether his Prayer is accepted or not. However, one should think good that Almighty Allah will accept his Prayer as well as all his good deeds. At the same time one should be keen to learn the proper way of performing Prayer and to have sincerity and good intention and concentration while performing it.
So, we should do our best to offer Prayer in the proper and leave its acceptance to Allah Who is the only One Who knows our intentions.
