Random ḥadīth in Nasāʾī's Kubrá
"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 صَلَاةَ الْمَغْرِبِ وَالْعِشَاءِ صَلَّاهُمَا بِجَمْعٍ وَصَلَّى الْفَجْرَ يَوْمَئِذٍ قَبْلَ مِيقَاتِهَا»
