[Machine] The Messenger of Allah ﷺ witnessed and a man asked him, as if he were a Bedouin, "O Messenger of Allah, what do you think of a man who touches his private parts after performing ablution?" He replied, "Is it anything other than a part of you or a portion of you?"  

شَهِدَتُ رَسُولَ اللهِ ﷺ وَسَأَلَهُ رَجُلٌ كَأَنَّهُ بَدْوِيٌّ فَقَالَ يَا رَسُولَ اللهِ مَا تَرَى فِي الرَّجُلِ يَمَسُّ ذَكَرَهُ بَعْدَمَا يَتَوَضَّأُ؟ فَقَالَ «هَلْ هُوَ إِلَّا مُضْغَةٌ مِنْكَ أَوْ بَضْعَةٌ؟»  

"We went out as a delegation and when we arrived with the Messenger of Allah ﷺ he accepted our oath of allegiance and we prayed with him. When he had finished the prayer, a man who looked like a Bedouin came to him and said: 'O Messenger of Allah, what do you think about a man who touched his penis during the Salah?' He said: 'It is just a part of you,' or 'a piece of you.'" (Using translation from Nasāʾī 165)  

خَرَجْنَا وَفْدًا حَتَّى قَدِمْنَا عَلَى رَسُولِ اللهِ ﷺ فَبَايَعْنَاهُ وَصَلَّيْنَا مَعَهُ فَلَمَّا قَضَى الصَّلَاةَ جَاءَ رَجُلٌ كَأَنَّهُ بَدَوِيٌّ فَقَالَ يَا نَبِيَّ اللهِ مَا تَرَى فِي رَجُلٍ مَسَّ ذَكَرَهُ فِي الصَّلَاةِ؟ قَالَ «وَهَلْ هُوَ إِلَّا مُضْغَةٌ مِنْكَ أَوْ بِضْعَةٌ مِنْكَ؟»  

" خَرَجْنَا وَفْدًا حَتَّى قَدِمْنَا عَلَى نَبِىِّ الله ﷺ فَبَايَعْنَا، فَصَلَّيْنا، فجاءَ رَجُل فَقَالَ: يَا رَسُولَ الله: مَا تَرى في مَسِّ الذَّكَرِ في الصَّلاَةِ؟ فَقَالَ: وَهَلْ هُوَ إِلَّا بَضْعَة منْكَ".
