Muwatta Imam Malik Book of Hajj, Hadith 75
Yahya related to me from Malik, from Yahya ibn Sa'id, from Sulayman ibn Yasar, that the Messenger of Allah ﷺ was once cupped on the top of his head while he was in ihram, at Lahyay Jamal, which is a place on the road to Makka.
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، أَنَّ رَسُولَ اللَّهِ ﷺ احْتَجَمَ وَهُوَ مُحْرِمٌ فَوْقَ رَأْسِهِ وَهُوَ يَوْمَئِذٍ بِلَحْيَىْ جَمَلٍ مَكَانٌ بِطَرِيقِ مَكَّةَ .
