Ibn Mas’ud said “ I never saw the Apostle of Allaah ﷺ observe a prayer out of its proper time except(two prayers) at Al Muzdalifah. He combined the sunset and night prayers at Al Muzdalifah and he offered the dawn prayer that day before its proper time.
مَا رَأَيْتُ رَسُولَ اللَّهِ ﷺ صَلَّى صَلاَةً إِلاَّ لِوَقْتِهَا إِلاَّ بِجَمْعٍ فَإِنَّهُ جَمَعَ بَيْنَ الْمَغْرِبِ وَالْعِشَاءِ بِجَمْعٍ وَصَلَّى صَلاَةَ الصُّبْحِ مِنَ الْغَدِ قَبْلَ وَقْتِهَا
