When the prophet Muhammad (SAW) went on the night journey of Israh and Mi3raaj, what are he three amounts of praying that were mentioned in the hadith.
Fifty, forty, five
"Then fifty prayers were enjoined on me. 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. When I came to Moses again, he said, 'What have you done?' I said, 'Allah has made it five only.' He repeated the same advice but I said that I surrendered (to Allah's Final Order)'" Allah's Apostle was addressed by Allah, "I have decreed My Obligation and have reduced the burden on My slaves, and I shall reward a single good deed as if it were ten good deeds." (Sahih Bukhari)
