Sahih al-Bukhari 565
Narrated Muhammad bin `Amr:
We asked Jabir bin `Abdullah about the prayers of the Prophet (ﷺ) . He said, "He used to pray Zuhr prayer 
at midday, the `Asr when the sun was still hot, and the Maghrib after sunset (at its stated time). The 
`Isha was offered early if the people gathered, and used to be delayed if their number was less; and the 
morning prayer was offered when it was still dark. "
حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ سَعْدِ بْنِ إِبْرَاهِيمَ، عَنْ مُحَمَّدِ بْنِ عَمْرٍو ـ هُوَ ابْنُ الْحَسَنِ بْنِ عَلِيٍّ ـ قَالَ سَأَلْنَا جَابِرَ بْنَ عَبْدِ اللَّهِ عَنْ صَلاَةِ النَّبِيِّ، صلى الله عليه وسلم فَقَالَ كَانَ يُصَلِّي الظُّهْرَ بِالْهَاجِرَةِ، وَالْعَصْرَ وَالشَّمْسُ حَيَّةٌ، وَالْمَغْرِبَ إِذَا وَجَبَتْ، وَالْعِشَاءَ إِذَا كَثُرَ النَّاسُ عَجَّلَ، وَإِذَا قَلُّوا أَخَّرَ، وَالصُّبْحَ بِغَلَسٍ‏.‏
