"I descended till I met Moses who asked me, 'What have you done?' I said, 'Fifty prayers have been enjoined on me.' He said, 'I know the people better than you, because I had the hardest experience to bring Bani Israel to obedience. Your followers cannot put up with such obligation. So, return to your Lord and request Him (to reduce the number of prayers.' I returned and requested Allah (for reduction) and He made it forty. I returned and (met Moses) and had a similar discussion, and then returned again to Allah for reduction and He made it thirty, then twenty, then ten, and then I came to Moses who repeated the same advice. Ultimately Allah reduced it to five."
