It is related that when the sinner shuts the door, lowers the curtain, closes the window, and gets down to sin, the earth will say, “O Lord, allow me to swallow him up!” and the sky will say, “Allow me to fall upon him!”

The glorious and exalted Lord will reply, “If the servant is your servant, then do with him what you will. But if he is My servant, then leave him alone. For if he comes to Me in the darkest of night, I will accept him, and if he comes to Me in the brightest of day, I will accept him. There is no gatekeeper or warden blocking My door, and whenever he comes to Me, he will find a path. when- ever he calls, ‘My Lord?’ I answer, ‘My servant!’ and whenever he says, ‘I have sinned, O, Lord!’ I reply, ‘I have forgiven you, My servant!”
