I never saw the Prophet ﷺ offering any prayer not at its stated time except two; he prayed the Maghrib and the ʿIsha' together and he offered the morning prayer before its usual time.
مَا رَأَيْتُ النَّبِيَّ ﷺ صَلَّى صَلاَةً بِغَيْرِ مِيقَاتِهَا إِلاَّ صَلاَتَيْنِ جَمَعَ بَيْنَ الْمَغْرِبِ وَالْعِشَاءِ وَصَلَّى الْفَجْرَ قَبْلَ مِيقَاتِهَا
I have never seen Messenger of Allah, ﷺ but observing the prayers at their appointed times except two prayers, sunset and 'Isha, ' at Muzdalifa (where he deferred the sunset prayer to combine it with 'Isha' and he observed the dawn prayer before its stipulated time on that day (10th of Dhu'l-Hijja).
مَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ صَلَّى صَلاَةً إِلاَّ لِمِيقَاتِهَا إِلاَّ صَلاَتَيْنِ صَلاَةَ الْمَغْرِبِ وَالْعِشَاءِ بِجَمْعٍ وَصَلَّى الْفَجْرَ يَوْمَئِذٍ قَبْلَ مِيقَاتِهَا
"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.
مَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ صَلَّى صَلاَةً قَطُّ إِلاَّ لِمِيقَاتِهَا إِلاَّ صَلاَةَ الْمَغْرِبِ وَالْعِشَاءِ صَلاَّهُمَا بِجَمْعٍ وَصَلاَةَ الْفَجْرِ يَوْمَئِذٍ قَبْلَ مِيقَاتِهَا
