Bulugh al-Maram 1 The Book of Purification كتاب الطهارة 50

وَهُوَ عِنْدَ “مُسْلِمٍ” مِنْ هَذَا اَلْوَجْهِ بِلَفْظٍ: وَمَسَحَ بِرَأْسِهِ بِمَاءٍ غَيْرَ فَضْلِ يَدَيْهِ, وَهُوَ اَلْمَحْفُوظ ُ 1 . 1 – صحيح. رواه مسلم (236)، وقال البيهقي: “وهذا أصح من الذي قبله” .

And the words of the Muslim version are: “he wiped his head taking extra water from that he had taken for the washing of the hands”, and this Hadith is Al-Mahfuz.
