وَعَنْ جَابِرِ بْنِ سَمُرَةَ قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقْرَأُ فِي صَلَاةِ الْمَغْرِبِ لَيْلَةَ الْجُمُعَةِ: (قُلْ يَا أَيُّهَا الْكَافِرُونَ) و (قل هُوَ الله أحد) رَوَاهُ فِي شرح السّنة وَرَوَاهُ ابْنُ مَاجَهْ عَنِ ابْنِ عُمَرَ إِلَّا أَنه لم يذكر «لَيْلَة الْجُمُعَة»
