«ما من مسلم يتطهر فيتم الطهور الذي كتب الله عليه فيصلي هذه الصلوات الخمس إلا كانت كفارة لما بينهن»
The Prophet (peace and blessings be upon him) said:
"Whichever Muslim purifies himself and completes the purification that Allah has made obligatory upon him, then prays these five prayers, these prayers become an expiation for (the sins) between them."
