Narrated Jabir bin `Abdullah:
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ ، قَالَ حَدَّثَنَا شُعْبَةُ ، عَنْ سَعْدٍ ، عَنْ مُحَمَّدِ بْنِ عَمْرِو بْنِ الْحَسَنِ بْنِ عَلِيٍّ ، قَالَ قَدِمَ الْحَجَّاجُ فَسَأَلْنَا جَابِرَ بْنَ عَبْدِ اللَّهِ فَقَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم يُصَلِّي الظُّهْرَ بِالْهَاجِرَةِ، وَالْعَصْرَ وَالشَّمْسُ نَقِيَّةٌ، وَالْمَغْرِبَ إِذَا وَجَبَتْ، وَالْعِشَاءَ أَحْيَانًا وَأَحْيَانًا، إِذَا رَآهُمُ اجْتَمَعُوا عَجَّلَ، وَإِذَا رَآهُمْ أَبْطَوْا أَخَّرَ، وَالصُّبْحَ كَانُوا ـ أَوْ كَانَ النَّبِيُّ صلى الله عليه وسلم يُصَلِّيهَا بِغَلَسٍ.
The Prophet (ﷺ) used to pray the Zuhr at midday, and the `Asr at a time when the sun was still bright, the Maghrib after sunset (at its stated time) and the `Isha at a variable time. Whenever he saw the people assembled (for `Isha' prayer) he would pray earlier and if the people delayed, he would delay the prayer. And they or the Prophet (ﷺ) used to offer the Fajr Prayers when it still dark.
