حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا أَبُو شِهَابٍ، عَنْ عَاصِمٍ، عَنْ عِكْرِمَةَ، عَنِ ابْنِ عَبَّاسٍ، قَالَ أَقَمْنَا مَعَ النَّبِيِّ صلى الله عليه وسلم فِي سَفَرٍ تِسْعَ عَشْرَةَ نَقْصُرُ الصَّلاَةَ. وَقَالَ ابْنُ عَبَّاسٍ وَنَحْنُ نَقْصُرُ مَا بَيْنَنَا وَبَيْنَ تِسْعَ عَشْرَةَ، فَإِذَا زِدْنَا أَتْمَمْنَا.
