[Machine] Narrated Aisha, the wife of the Prophet ﷺ : She said, "The first thing that was ordained upon the Messenger of Allah ﷺ was the prayer, two rak'ahs, two rak'ahs, except Maghrib, which was three rak'ahs. Then Allah completed Dhuhr, Asr, Isha in fours while in his presence. And He made the prayer obligatory in its initial (number of) units during travel."
عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ قَالَ قَالَتْ كَانَ أَوَّلَ مَا افْتُرِضَ عَلَى رَسُولِ اللهِ ﷺ الصَّلَاةُ رَكْعَتَانِ رَكْعَتَانِ إِلَّا الْمَغْرِبَ فَإِنَّهَا كَانَتْ ثَلَاثًا ثُمَّ أَتَمَّ اللهُ الظُّهْرَ وَالْعَصْرَ وَالْعِشَاءَ الْآخِرَةَ أَرْبَعًا فِي الْحَضَرِ وَأَقَرَّ الصَّلَاةَ عَلَى فَرْضِهَا الْأَوَّلِ فِي السَّفَرِ
