Mishkat al-Masabih 588
Muhammad b. ‘Amr b. al-Hasan b. ‘Ali said:
We asked Jabir b. ‘Abdallah about the Prophet’s observance of prayer and he said, “He used to pray the noon prayer in the midday heat; the afternoon prayer when the sun was bright; the sunset prayer when the sun had completely set; the night prayer early if many were present, but late if there were few; and the dawn prayer just before daybreak.” 

(Bukhari and Muslim)
وَعَن مُحَمَّد بن عَمْرو هُوَ ابْن الْحَسَنِ بْنِ عَلِيٍّ قَالَ: سَأَلْنَا جَابِرَ بْنَ عَبْدِ اللَّهِ عَنْ صَلَاةِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ كَانَ يُصَلِّي الظُّهْرَ بِالْهَاجِرَةِ وَالْعَصْرَ وَالشَّمْسُ حَيَّةٌ وَالْمَغْرِبَ إِذَا وَجَبَتْ وَالْعِشَاءَ إِذَا كَثُرَ النَّاسُ عَجَّلَ وَإِذَا قَلُّوا أَخَّرَ وَالصُّبْح بِغَلَس
