حَدَّثَنَا عُمَرُ بْنُ حَفْصِ بْنِ غِيَاثٍ، حَدَّثَنَا أَبِي، حَدَّثَنَا الأَعْمَشُ، قَالَ حَدَّثَنِي عُمَارَةُ، عَنْ عَبْدِ الرَّحْمَنِ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه ـ قَالَ مَا رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم صَلَّى صَلاَةً بِغَيْرِ مِيقَاتِهَا إِلاَّ صَلاَتَيْنِ جَمَعَ بَيْنَ الْمَغْرِبِ وَالْعِشَاءِ، وَصَلَّى الْفَجْرَ قَبْلَ مِيقَاتِهَا.
