Useful in purifying the limbs

God says, O brother of messengers and brother of warners, meaning our master Muhammad, may God bless him and grant him peace, a commandment that he conveys to us from his Lord Almighty, that you do not enter any of my houses except with hearts. Healthy tongues, honest tongues, pure hands, and clean genitals, and do not enter any of My houses. And if any of My servants has any injustice with any of them, then which slave, as long as he stands before me and prays, I will not accept his prayer until he returns that injustice to its people. If he does, then I will be his hearing with which he hears and I will be his sight with which he sees and he will be. He is one of my saints and my pure ones, and he will be my neighbor with the prophets, the truthful ones, and the martyrs in Paradise.
