أَخْبَرَنَا يَعْقُوبُ بْنُ مَاهَانَ، قَالَ حَدَّثَنَا الْقَاسِمُ بْنُ مَالِكٍ، عَنْ أَيُّوبَ بْنِ عَائِذٍ، عَنْ بُكَيْرِ بْنِ الأَخْنَسِ، عَنْ مُجَاهِدٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ إِنَّ اللَّهَ عَزَّ وَجَلَّ فَرَضَ الصَّلاَةَ عَلَى لِسَانِ نَبِيِّكُمْ صلى الله عليه وسلم فِي الْحَضَرِ أَرْبَعًا وَفِي السَّفَرِ رَكْعَتَيْنِ وَفِي الْخَوْفِ رَكْعَةً ‏.‏
