Gabriel (Jibra'eal) said to me: 'This is your father; pay your greetings to him.' So I greeted him and he returned the greetings to me and said: 'You are welcomed, O pious son and pious Prophet.' Then I was made to ascend to Sidrat-ul-Muntaha (the Lote Tree of the utmost boundary). Behold! Its fruits were like the jars of Hajr (a place near Medina ) and its leaves were as big as the ears of elephants. Gabriel (Jibra'eal) said: "This is the Lote Tree of the utmost and boundary.' Behold! There ran four rivers, two were hidden and two were visible, I asked: 'What are these two kinds of rivers, O Gabriel (Jibra'eal)?' He replied: 'As for the hidden rivers, they are two rivers in Paradise and the visible rivers are the Nile and the Euphrates . "Then Al-Bait-ul-Ma'mur (the Sacred House) was shown to me and a container full of wine and another full of milk and a third full of honey were brought to me. I took the milk. Gabriel (Jibra'eal) remarked: 'This is the Islamic religion which you and your followers are following.' Then the prayers were enjoined on me: they were fifty prayers a day. When I returned, I passed by Moses, who asked me; 'What have you been ordered to do?' I replied: 'I have been ordered to offer fifty prayers a day.' Moses said: 'Your followers cannot bear fifty prayers a day, and by Allah I have tested people before you, and I have tried my level best with Children of Israel (Children of Israel (Bani-al-Israel)) in vain. Go back to your Lord and ask for reduction to lessen your followers'' burden.' So I went back, and Allah reduced ten prayers for me. Then again I came to Moses, but he repeated the same as he had said before. Then again I went back to Allah, and He reduced ten more prayers. When I came to Moses he said the same. I went back to Allah, and He ordered m to observe ten prayers a day. When I came back to Moses, he repeated the same advice, so I went back to Allah and was ordered to observe five prayers a day. "When I came back to Moses, he said: 'What have you been ordered?' I replied: 'I have been ordered to observe five prayers a day.' He said: 'Your followers cannot bear five prayers a day, and no doubt, I have got an experience of the people before you, and I have tried my level best with Children of Israel (Bani-al-Israel), so go back to your Lord and ask for reduction to lesson your followers' burden.' I said: 'I have requested so much of my Lord that I feel ashamed, but I am satisfied now and surrender to Allah's Order.' When I left, I heard a voice saying: 'I have passed My order and have lessened the burden of My worshippers.'"
