Sunan an-Nasai
أَخْبَرَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، قَالَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ عُمَارَةَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ يَزِيدَ، عَنْ عَبْدِ اللَّهِ، قَالَ مَا رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم صَلَّى صَلاَةً قَطُّ إِلاَّ لِمِيقَاتِهَا إِلاَّ صَلاَةَ الْمَغْرِبِ وَالْعِشَاءِ صَلاَّهُمَا بِجَمْعٍ وَصَلاَةَ الْفَجْرِ يَوْمَئِذٍ قَبْلَ مِيقَاتِهَا .
It was narrated that Abdullah said: "I never saw the Messenger of Allah offer any prayer except at the proper time, apart from Maghrib and Isha in Jam (Al-Muzdalifah) and Fajir on that day, which he offered before the usual time.
