And al-Uwaisi said: Muhammad bin Ja'far narrated the hadith to me, from Yahya bin Sa'id and Sharik, both of them heard from Hazrat Anas (Allāh be pleased with him), from the Prophet ﷺ, that
he ﷺ raised both his hands, to the extent that I saw the whiteness (of the place) of his armpits.
وَقَالَ الأُوَيْسِيُّ: حَدَّثَنِي مُحَمَّدُ بْنُ جَعْفَرٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، وَشَرِيكٍ، سَمِعَا أَنَسًا، عَنِ النَّبِيِّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ: «أَنَّهُ رَفَعَ يَدَيْهِ حَتَّى رَأَيْتُ بَيَاضَ إِبْطَيْهِ
