حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا شُعَيْبُ بْنُ إِسْحَاقَ، عَنِ الأَوْزَاعِيِّ، قَالَ حَدَّثَنِي يَحْيَى، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، عَنْ عُمَرَ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " اللَّيْلَةَ أَتَانِي آتٍ مِنْ رَبِّي وَهْوَ بِالْعَقِيقِ أَنْ صَلِّ فِي هَذَا الْوَادِي الْمُبَارَكِ وَقُلْ عُمْرَةٌ فِي حَجَّةٍ " .
