Bulugh al-Maram, Book 1, Hadith 48 (English) ⓘ

Narrated ‘Abdullah bin Zaid (rad): He saw the Prophet taking some water to wipe his ears other than the water he had taken to wipe his head. [Reported by Al-Baihaqi, who said that its Isnad (chain of narrators) is authentic and At-Tirmidhi also graded it Sahih].

وَعَنْهُ, { أَنَّهُ رَأَى اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-يَأْخُذُ لِأُذُنَيْهِ مَاءً خِلَافَ اَلْمَاءِ اَلَّذِي أَخَذَ لِرَأْسِهِ.‏ } أَخْرَجَهُ اَلْبَيْهَقِيّ ُ (54)‏.‏ ‏5 ‏- البيهقي (1 /65)‏ وقال: "هذا إسناد صحيح".‏

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.

وَهُوَ عِنْدَ "مُسْلِمٍ" مِنْ هَذَا اَلْوَجْهِ بِلَفْظٍ: وَمَسَحَ بِرَأْسِهِ بِمَاءٍ غَيْرَ فَضْلِ يَدَيْهِ, وَهُوَ اَلْمَحْفُوظ ُ (55)‏.‏ ‏1 ‏- صحيح.‏ رواه مسلم (236)‏، وقال البيهقي: "وهذا أصح من الذي قبله".‏
