الكبرى للنسائي:٧٥٨٣أَخْبَرَنَا أَبُو دَاوُدَ قَالَ حَدَّثَنَا عُثْمَانُ بْنُ عُمَرَ قَالَ أَخْبَرَنَا يُونُسُ عَنِ الزُّهْرِيِّ عَنِ ابْنِ خُزَيْمَةَ عَنْ عَمِّهِ أَخِي خُزَيْمَةَ رَأَى فِيمَا يَرَى النَّائِمُ

أَنَّهُ يَسْجُدُ عَلَى جَبْهَةِ النَّبِيِّ ﷺ فَذَكَرَ ذَلِكَ لَهُ فَاضْطَجَعَ لَهُ وَقَالَ «صَدِّقْ رُؤْيَاكَ» فَسَجَدَ عَلَى جَبْهَتِهِ
