Narrated ‘Abdullah bin Zaid (rad):
He saw the Prophet (ﷺ) 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 ُ 1‏ .‏


‏1 ‏- البيهقي (1 /65)‏ وقال: "هذا إسناد صحيح".‏
