Muwatta Malik #810
Hajj
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ سُلَيْمَانَ بْنِ يَسَارٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم احْتَجَمَ وَهُوَ مُحْرِمٌ فَوْقَ رَأْسِهِ وَهُوَ يَوْمَئِذٍ بِلَحْيَىْ جَمَلٍ مَكَانٌ بِطَرِيقِ مَكَّةَ .
Yahya related to me from Malik, from Yahya ibn Sa'id, from
Sulayman ibn Yasar, that the Messenger of Allah, may Allah bless him
and grant him peace, 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.
