8/1. Chapter:
How As-Salat (the Prayer) was prescribed on the night of Al-Isra (miraculous night journey) of the Prophet (pbuh) to Jerusalem (and then to the heavens)
وَقَالَ ابْنُ عَبَّاسٍ حَدَّثَنِي أَبُو سُفْيَانَ فِي حَدِيثِ هِرَقْلَ فَقَالَ يَأْمُرُنَا- يَعْنِي النَّبِيَّ- صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِالصَّلاَةِ وَالصِّدْقِ وَالْعَفَافِ.Ibn ‘Abbas said: Abu Sufyan, when telling the narration of Heraclius, mentioned: “The Prophet ﷺ ordered us to offer our Salat (prayers) regularly and to be true and chaste.”

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، قَالَ أَخْبَرَنَا مَالِكٌ، عَنْ صَالِحِ بْنِ كَيْسَانَ، عَنْ عُرْوَةَ بْنِ الزُّبَيْرِ، عَنْ عَائِشَةَ أُمِّ الْمُؤْمِنِينَ، قَالَتْ " فَرَضَ اللَّهُ الصَّلاَةَ حِينَ فَرَضَهَا رَكْعَتَيْنِ رَكْعَتَيْنِ فِي الْحَضَرِ وَالسَّفَرِ، فَأُقِرَّتْ صَلاَةُ السَّفَرِ، وَزِيدَ فِي صَلاَةِ الْحَضَرِ ".
Narrated `Aisha: the mother of believers: Allah enjoined the prayer when He enjoined it, it was two rak`at only (in every prayer) both when in residence or on journey. Then the prayers offered on journey remained the same, but (the rak`at of) the prayers for non-travelers were increased.
