His father reported, We came to the Prophet of Allah ﷺ, and a man who appeared to be a bedouin came and said, "Prophet of Allah, what do you say about a man touching his penis after he has performed ablution?"He replied, "Is it anything but a piece of him?" Or he said, "A part of him?"
حدثنا مسدد حدثنا ملازم بن عمرو الحنفي حدثنا عبد الله بن بدر
عن أبيه قال قدمنا على نبي الله ﷺ فجاء رجل كأنه بدوي فقال يا نبي الله ما ترى في مس الرجل ذكره بعد ما يتوضأ فقال هل هو إلا مضغة منه أو قال بضعة منه
[Its isnad is sahih] Tirmidhi narrated it in the Book of Purification, in the chapter on what has been said about not performing wudu after touching the penis, hadith 85, from the hadith of Mulazim bin Amr, with this wording. Ibn Hibban and others have established that this hadith is abrogated.
