A person happened to pass by the Messenger of Allah ﷺ when he was making water and saluted him, but he did not respond to his salutation.
أَنَّ رَجُلاً مَرَّ وَرَسُولُ اللَّهِ ﷺ يَبُولُ فَسَلَّمَ فَلَمْ يَرُدَّ عَلَيْهِ
"A man passed by the Prophet ﷺ when he was urinating and greeted him with Salam, but he did not return his greeting."
مَرَّ رَجُلٌ عَلَى النَّبِيِّ ﷺ وَهُوَ يَبُولُ فَسَلَّمَ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيْهِ السَّلاَمَ
A man passed by the Prophet (sal Allaahu alayhi wa sallam ) while he was urinating, and saluted him. The Prophet (sal Allaahu alayhi wa sallam) did not return the salutation to him. Abu Dawud said : It is narrated on the authority of Ibn 'Umar that the Prophet (sal Allaahu alayhi wa sallam) performed tayammum, then he returned the salutation to the man.
مَرَّ رَجُلٌ عَلَى النَّبِيِّ ﷺ وَهُوَ يَبُولُ فَسَلَّمَ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيْهِ
"A man greeted the Prophet (with Salam), and he was urinating, so he did not respond to him."
أَنَّ رَجُلاً سَلَّمَ عَلَى النَّبِيِّ ﷺ وَهُوَ يَبُولُ فَلَمْ يَرُدَّ عَلَيْهِ
"A man passed by the Prophet while he was urinating and greeted him with the Salam, and he did not return the greeting."
مَرَّ رَجُلٌ عَلَى النَّبِيِّ ﷺ وَهُوَ يَبُولُ فَسَلَّمَ عَلَيْهِ فَلَمْ يَرُدَّ عَلَيْهِ
A man wearing two red garments passed the Prophet ﷺ and gave him a greeting, but he did not respond to his greeting. (Using translation from Abū Dāʾūd 4069)
«مَرَّ عَلَى النَّبِيِّ ﷺ رَجُلٌ وَعَلَيْهِ ثَوْبَانِ أَحْمَرَانِ فَسَلَّمَ فَلَمْ يَرُدَّ عَلَيْهِ رَسُولُ اللَّهِ ﷺ»
