The Messenger of Allah ﷺ performed ablution in her presence. He wiped the whole of his head from its upper to the lower part moving every side. He did not move the hair from their original position. (Using translation from Abū Dāʾūd 128)   

أَنَّ رَسُولَ اللهِ ﷺ تَوَضَّأَ عِنْدَهَا فَمَسَحَ بِرَأْسِهِ فَمَسَحَ الرَّأْسَ كُلَّهُ مِنْ فَوْقِ الشَّعْرِ كُلَّ نَاحِيَةٍ لِمُنْصَبِّ الشَّعْرِ لَا يُحَرِّكُ الشَّعْرَ عَنْ هَيْئَتِهِ وَفِي رِوَايَةٍ غَيْرِهَا مِنْ قَرْنِ الشَّعْرِ  

[Machine] And Abu Abdullah said, "This is the meaning of the hadith of Rabi'i, they both convey the same message and do not alter the course of the poetry."  

وَقَالَ أَبُو عَبْدِ اللهِ هَذَا وَحَدِيثُ الرُّبَيِّعِ مَعْنَاهُمَا وَاحِدٌ لَا يُقَلِّبُ الشَّعْرَ عَنْ مَجَارِيهِ
