أَخْبَرَنَا حُمَيْدُ بْنُ مَسْعَدَةَ، عَنْ سُفْيَانَ، - وَهُوَ ابْنُ حَبِيبٍ - عَنْ شُعْبَةَ، عَنِ النُّعْمَانِ بْنِ سَالِمٍ، عَنِ ابْنِ أَبِي أَوْسٍ، عَنْ جَدِّهِ، قَالَ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم اسْتَوْكَفَ ثَلاَثًا ‏.‏

It was narrated from (Aws bin) Abi Aws that his grandfather said

"I saw the Messenger of Allah (ﷺ) trickle water into his hand until it started to drip from his hand, three times."
