حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، وَمُحَمَّدُ بْنُ إِسْمَاعِيلَ، قَالاَ حَدَّثَنَا وَكِيعٌ، عَنْ سُفْيَانَ، عَنْ هِشَامِ بْنِ إِسْحَاقَ بْنِ عَبْدِ اللَّهِ بْنِ كِنَانَةَ، عَنْ أَبِيهِ، قَالَ أَرْسَلَنِي أَمِيرٌ مِنَ الأُمَرَاءِ إِلَى ابْنِ عَبَّاسٍ أَسْأَلُهُ عَنِ الصَّلاَةِ، فِي الاِسْتِسْقَاءِ فَقَالَ ابْنُ عَبَّاسٍ مَا مَنَعَهُ أَنْ يَسْأَلَنِي، قَالَ خَرَجَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ مُتَوَاضِعًا مُتَبَذِّلاً مُتَخَشِّعًا مُتَرَسِّلاً مُتَضَرِّعًافَصَلَّى رَكْعَتَيْنِ كَمَا يُصَلِّي فِي الْعِيدِ وَلَمْ يَخْطُبْ خُطْبَتَكُمْ هَذِهِ ‏.‏
