Hadith 899
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ النُّفَيْلِيُّ، حَدَّثَنَا زُهَيْرٌ، حَدَّثَنَا أَبُو إِسْحَاقَ، عَنِ التَّمِيمِيِّ الَّذِي، يُحَدِّثُ بِالتَّفْسِيرِ عَنِ ابْنِ عَبَّاسٍ، قَالَ أَتَيْتُ النَّبِيَّ صلى الله عليه وسلم مِنْ خَلْفِهِ فَرَأَيْتُ بَيَاضَ إِبْطَيْهِ وَهُوَ مُجَخٍّ قَدْ فَرَّجَ بَيْنَ يَدَيْهِ .
Narrated Abdullah ibn Abbas:
I came to the Prophet (ﷺ) from behind. I saw the whiteness of his armpits and he kept his arms away from his sides and raised his stomach (from the ground).
