Ibn Abbis (Allah be pleased with him) reported that Mu'awiya b. Abu Safyin had told him:

I clipped the hair (from the head of) Allah's Messenger (ﷺ) with a clipper while he was at al-Marwa, or I saw him getting his hair clipped with a clipper as he was at al-Marwa. 1722

وَحَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، عَنِ ابْنِ جُرَيْجٍ، حَدَّثَنِي الْحَسَنُ، بْنُ مُسْلِمٍ عَنْ طَاوُسٍ، عَنِ ابْنِ عَبَّاسٍ، أَنَّ مُعَاوِيَةَ بْنَ أَبِي سُفْيَانَ، أَخْبَرَهُ قَالَ قَصَّرْتُ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم بِمِشْقَصٍ وَهُوَ عَلَى الْمَرْوَةِ أَوْ رَأَيْتُهُ يُقَصَّرُ عَنْهُ بِمِشْقَصٍ وَهُوَ عَلَى الْمَرْوَةِ ‏.‏
