Had I known at the start what I came to know later, no one would have washed the Prophet ﷺ except his wives.
حدثنا محمد بن يحيى حدثنا أحمد بن خالد الذهبي حدثنا محمد بن إسحق عن يحيى بن عباد بن عبد الله بن الزبير عن أبيه
لو كنت استقبلت من أمري ما استدبرت ما غسل النبي ﷺ غير نسائه
[Its chain is hasan] Reported by Abu Dawud, Funerals, chapter on covering the deceased while washing, no. 3141, and Ahmad, 6/267, from the hadith of Muhammad bin Ishaq with this wording, and he explicitly stated that he heard it directly. Ibn Jabban, Hakim, Dhahabi, and others graded it sahih with this wording.
