Sahih al-Bukhari, Volume 1, Book 11, Hadith 668 (USC-MSA) ⓘ
Narrated Mu`adh bin Jabal: I used to pray the `Isha prayer with the Prophet and then go to lead my people in the prayer.
حَدَّثَنَا مُسْلِمٌ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ عَمْرٍو، عَنْ جَابِرِ بْنِ عَبْدِ اللَّهِ، أَنَّ مُعَاذَ بْنَ جَبَلٍ، كَانَ يُصَلِّي مَعَ النَّبِيِّ صلى الله عليه وسلم ثُمَّ يَرْجِعُ فَيَؤُمُّ قَوْمَهُ.
