Sahih Muslim 1205
Sahih Muslim · Book 15: The Book of Pilgrimage · It is permissible for the Muhrim to wash his body and head
This hadith has been narrated on the authority of Zaid b. Aslam with the same chain of transmitters that Abu Ayyub rubbed his whole head with his hands and then moved them forward and backward. Miswar said to Ibn 'Abbas:
وَحَدَّثَنَاهُ إِسْحَاقُ بْنُ إِبْرَاهِيمَ ، وَعَلِيُّ بْنُ خَشْرَمٍ ، قَالاَ أَخْبَرَنَا عِيسَى بْنُ يُونُسَ ، حَدَّثَنَا ابْنُ جُرَيْجٍ ، أَخْبَرَنِي زَيْدُ بْنُ أَسْلَمَ ، بِهَذَا الإِسْنَادِ وَقَالَ فَأَمَرَّ أَبُو أَيُّوبَ بِيَدَيْهِ عَلَى رَأْسِهِ جَمِيعًا عَلَى جَمِيعِ رَأْسِهِ فَأَقْبَلَ بِهِمَا وَأَدْبَرَ فَقَالَ الْمِسْوَرُ لاِبْنِ عَبَّاسٍ لاَ أُمَارِيكَ أَبَدًا .
I would never dispute with you (in future).
