How As-Salat (the Prayer) was prescribed on the night of Al-Isra (miraculous night journey) of the Prophet ﷺ to Jerusalem (and then to the heavens)

Narrated Abu Dhar:

Allah's Apostle ﷺ said, "While I was at Mecca the roof of my house was opened and Gabriel descended, opened my chest, and washed it with Zam-zam water. Then he brought a golden tray full of wisdom and faith and having poured its contents into my chest, he closed it. Then he took my hand and ascended with me to the nearest heaven, when I reached the nearest heaven, Gabriel said to the gatekeeper of the heaven, 'Open (the gate).' The gatekeeper asked, 'Who is it?' Gabriel answered: 'Gabriel.' He asked, 'Is there anyone with you?' Gabriel replied, 'Yes, Muhammad I is with me.' He asked, 'Has he been called?' Gabriel said, 'Yes.' So the gate was opened and we went over the nearest heaven and there we saw a man sitting with some people on his right and some on his left. When he looked towards his right, he laughed and when he looked toward his left he wept. Then he said, 'Welcome! O pious Prophet and pious son.' I asked Gabriel, 'Who is he?' He replied, 'He is Adam and the people on his right and left are the souls of his offspring. Those on his right are the people of Paradise and those on his left are the people of Hell and when he looks towards his right he laughs and when he looks towards his left he weeps.' Then he ascended with me till he reached the second heaven and he (Gabriel) said to its gatekeeper, 'Open (the gate).' The gatekeeper said to him the same as the gatekeeper of the first heaven had said and he opened the gate. Anas said: "Abu Dhar added that the Prophet met Adam, Idris, Moses, Jesus and Abraham, he (Abu Dhar) did not mention on which heaven they were but he mentioned that he (the Prophet ) met Adarn on the nearest heaven and Abraham on the sixth heaven. Anas said, "When Gabriel along with the Prophet ﷺ passed by Idris, the latter said, 'Welcome! O pious Prophet and pious brother.' The Prophet asked, 'Who is he?' Gabriel replied, 'He is Idris." The Prophet added, "I passed by Moses and he said, 'Welcome! O pious Prophet and pious brother.' I asked Gabriel, 'Who is he?' Gabriel replied, 'He is Moses.' Then I passed by Jesus and he said, 'Welcome! O pious brother and pious Prophet.' I asked, 'Who is he?' Gabriel replied, 'He is Jesus. Then I passed by Abraham and he said, 'Welcome! O pious Prophet and pious son.' I asked Gabriel, 'Who is he?' Gabriel replied, 'He is Abraham. The Prophet added, 'Then Gabriel ascended with me to a place where I heard the creaking of the pens." Ibn Hazm and Anas bin Malik said: The Prophet ﷺ said, "Then Allah enjoined fifty prayers on my followers when I returned with this order of Allah, I passed by Moses who asked me, 'What has Allah enjoined on your followers?' I replied, 'He has enjoined fifty prayers on them.' Moses said, 'Go back to your Lord (and appeal for reduction) for your followers will not be able to bear it.' (So I went back to Allah and requested for reduction) and He reduced it to half. When I passed by Moses again and informed him about it, he said, 'Go back to your Lord as your followers will not be able to bear it.' So I returned to Allah and requested for further reduction and half of it was reduced. I again passed by Moses and he said to me: 'Return to your Lord, for your followers will not be able to bear it. So I returned to Allah and He said, 'These are five prayers and they are all (equal to) fifty (in reward) for My Word does not change.' I returned to Moses and he told me to go back once again. I replied, 'Now I feel shy of asking my Lord again.' Then Gabriel took me till we '' reached Sidrat-il-Muntaha (Lote tree of;
the utmost boundry) which was shrouded in colors, indescribable. Then I was admitted into Paradise where I found small (tents or) walls (made) of pearls and its earth was of musk."

حَدَّثَنَا يَحْيَى بْنُ بُكَيْرٍ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ يُونُسَ، عَنِ ابْنِ شِهَابٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كَانَ أَبُو ذَرٍّ يُحَدِّثُ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ " فُرِجَ عَنْ سَقْفِ بَيْتِي وَأَنَا بِمَكَّةَ، فَنَزَلَ جِبْرِيلُ فَفَرَجَ صَدْرِي، ثُمَّ غَسَلَهُ بِمَاءِ زَمْزَمَ، ثُمَّ جَاءَ بِطَسْتٍ مِنْ ذَهَبٍ مُمْتَلِئٍ حِكْمَةً وَإِيمَانًا، فَأَفْرَغَهُ فِي صَدْرِي ثُمَّ أَطْبَقَهُ، ثُمَّ أَخَذَ بِيَدِي فَعَرَجَ بِي إِلَى السَّمَاءِ الدُّنْيَا، فَلَمَّا جِئْتُ إِلَى السَّمَاءِ الدُّنْيَا قَالَ جِبْرِيلُ لِخَازِنِ السَّمَاءِ افْتَحْ. قَالَ مَنْ هَذَا قَالَ هَذَا جِبْرِيلُ. قَالَ هَلْ مَعَكَ أَحَدٌ قَالَ نَعَمْ مَعِي مُحَمَّدٌ ﷺ. فَقَالَ أُرْسِلَ إِلَيْهِ قَالَ نَعَمْ. فَلَمَّا فَتَحَ عَلَوْنَا السَّمَاءَ الدُّنْيَا، فَإِذَا رَجُلٌ قَاعِدٌ عَلَى يَمِينِهِ أَسْوِدَةٌ وَعَلَى يَسَارِهِ أَسْوِدَةٌ، إِذَا نَظَرَ قِبَلَ يَمِينِهِ ضَحِكَ، وَإِذَا نَظَرَ قِبَلَ يَسَارِهِ بَكَى، فَقَالَ مَرْحَبًا بِالنَّبِيِّ الصَّالِحِ وَالاِبْنِ الصَّالِحِ. قُلْتُ لِجِبْرِيلَ مَنْ هَذَا قَالَ هَذَا آدَمُ. وَهَذِهِ الأَسْوِدَةُ عَنْ يَمِينِهِ وَشِمَالِهِ نَسَمُ بَنِيهِ، فَأَهْلُ الْيَمِينِ مِنْهُمْ أَهْلُ الْجَنَّةِ، وَالأَسْوِدَةُ الَّتِي عَنْ شِمَالِهِ أَهْلُ النَّارِ، فَإِذَا نَظَرَ عَنْ يَمِينِهِ ضَحِكَ، وَإِذَا نَظَرَ قِبَلَ شِمَالِهِ بَكَى، حَتَّى عَرَجَ بِي إِلَى السَّمَاءِ الثَّانِيَةِ فَقَالَ لِخَازِنِهَا افْتَحْ. فَقَالَ لَهُ خَازِنُهَا مِثْلَ مَا قَالَ الأَوَّلُ فَفَتَحَ ". قَالَ أَنَسٌ فَذَكَرَ أَنَّهُ وَجَدَ فِي السَّمَوَاتِ آدَمَ وَإِدْرِيسَ وَمُوسَى وَعِيسَى وَإِبْرَاهِيمَ ـ صَلَوَاتُ اللَّهِ عَلَيْهِمْ ـ وَلَمْ يُثْبِتْ كَيْفَ مَنَازِلُهُمْ، غَيْرَ أَنَّهُ ذَكَرَ أَنَّهُ وَجَدَ آدَمَ فِي السَّمَاءِ الدُّنْيَا، وَإِبْرَاهِيمَ فِي السَّمَاءِ السَّادِسَةِ. قَالَ أَنَسٌ فَلَمَّا مَرَّ جِبْرِيلُ بِالنَّبِيِّ ﷺ بِإِدْرِيسَ قَالَ مَرْحَبًا بِالنَّبِيِّ الصَّالِحِ وَالأَخِ الصَّالِحِ. فَقُلْتُ مَنْ هَذَا قَالَ هَذَا إِدْرِيسُ. ثُمَّ مَرَرْتُ بِمُوسَى فَقَالَ مَرْحَبًا بِالنَّبِيِّ الصَّالِحِ وَالأَخِ الصَّالِحِ. قُلْتُ مَنْ هَذَا قَالَ هَذَا مُوسَى. ثُمَّ مَرَرْتُ بِعِيسَى فَقَالَ مَرْحَبًا بِالأَخِ الصَّالِحِ وَالنَّبِيِّ الصَّالِحِ. قُلْتُ مَنْ هَذَا قَالَ هَذَا عِيسَى. ثُمَّ مَرَرْتُ بِإِبْرَاهِيمَ فَقَالَ مَرْحَبًا بِالنَّبِيِّ الصَّالِحِ وَالاِبْنِ الصَّالِحِ. قُلْتُ مَنْ هَذَا قَالَ هَذَا إِبْرَاهِيمُ ﷺ ". قَالَ ابْنُ شِهَابٍ فَأَخْبَرَنِي ابْنُ حَزْمٍ أَنَّ ابْنَ عَبَّاسٍ وَأَبَا حَبَّةَ الأَنْصَارِيَّ كَانَا يَقُولاَنِ قَالَ النَّبِيُّ ﷺ " ثُمَّ عُرِجَ بِي حَتَّى ظَهَرْتُ لِمُسْتَوًى أَسْمَعُ فِيهِ صَرِيفَ الأَقْلاَمِ ". قَالَ ابْنُ حَزْمٍ وَأَنَسُ بْنُ مَالِكٍ قَالَ النَّبِيُّ ﷺ " فَفَرَضَ اللَّهُ عَلَى أُمَّتِي خَمْسِينَ صَلاَةً، فَرَجَعْتُ بِذَلِكَ حَتَّى مَرَرْتُ عَلَى مُوسَى فَقَالَ مَا فَرَضَ اللَّهُ لَكَ عَلَى أُمَّتِكَ قُلْتُ فَرَضَ خَمْسِينَ صَلاَةً. قَالَ فَارْجِعْ إِلَى رَبِّكَ، فَإِنَّ أُمَّتَكَ لاَ تُطِيقُ ذَلِكَ. فَرَاجَعْتُ فَوَضَعَ شَطْرَهَا، فَرَجَعْتُ إِلَى مُوسَى قُلْتُ وَضَعَ شَطْرَهَا. فَقَالَ رَاجِعْ رَبَّكَ، فَإِنَّ أُمَّتَكَ لاَ تُطِيقُ، فَرَاجَعْتُ فَوَضَعَ شَطْرَهَا، فَرَجَعْتُ إِلَيْهِ فَقَالَ ارْجِعْ إِلَى رَبِّكَ، فَإِنَّ أُمَّتَكَ لاَ تُطِيقُ ذَلِكَ، فَرَاجَعْتُهُ. فَقَالَ هِيَ خَمْسٌ وَهْىَ خَمْسُونَ، لاَ يُبَدَّلُ الْقَوْلُ لَدَىَّ. فَرَجَعْتُ إِلَى مُوسَى فَقَالَ رَاجِعْ رَبَّكَ. فَقُلْتُ اسْتَحْيَيْتُ مِنْ رَبِّي. ثُمَّ انْطَلَقَ بِي حَتَّى انْتَهَى بِي إِلَى سِدْرَةِ الْمُنْتَهَى، وَغَشِيَهَا أَلْوَانٌ لاَ أَدْرِي مَا هِيَ، ثُمَّ أُدْخِلْتُ الْجَنَّةَ، فَإِذَا فِيهَا حَبَايِلُ اللُّؤْلُؤِ، وَإِذَا تُرَابُهَا الْمِسْكُ ".
