البيهقي:٦٤٤٦أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ ثنا أَبُو عَبْدِ اللهِ مُحَمَّدُ بْنُ يَعْقُوبَ ثنا مُحَمَّدُ بْنُ عَبْدِ الْوَهَّابِ الْفَرَّاءُ أنبأ يَحْيَى بْنُ أَبِي بُكَيْرٍ ثنا شُعْبَةُ عَنْ ثَابِتٍ عَنْ أَنَسٍ قَالَ

رَأَيْتُ رَسُولَ اللهِ ﷺ يَرْفَعُ يَدَيْهِ فِي الدُّعَاءِ؛ حَتَّى يُرَى بَيَاضُ إِبْطَيْهِ يَعْنِي فِي الِاسْتِسْقَاءِ  

رَوَاهُ مُسْلِمٌ فِي الصَّحِيحِ عَنْ أَبِي بَكْرِ بْنِ أَبِي شَيْبَةَ عَنْ يَحْيَى بْنِ أَبِي بُكَيْرٍ
