عَنْ أَبِي إِسْحَاقَ عَنْ عَبْدِ الرَّحْمَنِ بْنِ يَزِيدَ قَالَ: كُنْتُ مَعَ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ بِجَمْعٍ فَصَلَّى الصَّلَاتَيْنِ كُلَّ صَلَاةٍ وَحْدَهَا بِأَذَانٍ وَإِقَامَةٍ وَالْعَشَاءُ بَيْنَهُمَا وَصَلَّى الْفَجْرَ حِينَ سَطَعَ الْفَجْرُ أَوْ قَالَ: حِينَ قَالَ قَائِلٌ طَلَعَ الْفَجْرُ وَقَالَ قَائِلٌ لَمْ يَطْلُعْ ثُمَّ قَالَ: إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ: ((إِنَّ هَاتَيْنِ الصَّلَاتَيْنِ تُحَوَّلَانِ عَنْ وَقْتِهِمَا فِي هَذَا الْمَكَانِ لَا يَقْدَمُ النَّاسُ جَمْعًا حَتَّى يُعْتِمُوا وَصَلَاةُ الْفَجْرِ هَذِهِ السَّاعَةَ))
Abdur Rahman bin Yazid says: I was with Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) at Muzdalifah when he performed both prayers with separate adhan and iqamah, and ate food between the two. Then, when dawn broke, he performed the Fajr prayer and after that said: The Messenger of Allah (peace and blessings be upon him) said: These two prayers (Maghrib and Fajr) are performed at this place at times different from the usual. When people reach Muzdalifah, it is quite late (so Maghrib is performed late), and the Fajr prayer is performed at this time.
