"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. (Using translation from Nasāʾī 3038)
مَا رَأَيْتُ رَسُولَ اللهِ ﷺ صَلَّى صَلَاةً قَطُّ إِلَّا لِمِيقَاتِهَا إِلَّا صَلَاتَيْنِ صَلَاةَ الْمَغْرِبِ وَصَلَاةَ الْعِشَاءِ بِجَمْعٍ وَصَلَّى الْفَجْرَ يَوْمَئِذٍ قَبْلَ مِيقَاتِهَا وقَالَ ابْنُ نُمَيْرٍ الْعِشَاءَيْنِ فَإِنَّهُ صَلَّاهُمَا بِجَمْعٍ جَمِيعًا
