“Each morning and night, ALLAH (swt) the exalted looks upon the white hairs of an old man and says: O my servant! You got old. Your bones have become fragile.
Your face is wrinkled. Your life is nearly over, and you are about to come to me. Be shy of me, as I am too shy of your white hair to torture you in the fire.”
