Sahih Muslim 845a

'Abdullah (b. 'Umar) reported from his father that while he was addressing the people on Friday (sermon), a person, one of the Companions of the Messenger of Allah ﷺ, entered (the mosque). Umar said to him loudly: What is this hour (for attending the prayer)? He said: I was busy today and I did not return to my house when I heard the call (to Friday prayer), and I did no more but performed ablution only. Upon this Umar said: just ablution! You know that the Messenger of Allah ﷺ commanded (us) to take a bath (on Friday).

وَحَدَّثَنِي حَرْمَلَةُ بْنُ يَحْيَى، أَخْبَرَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي يُونُسُ، عَنِ ابْنِ شِهَابٍ، حَدَّثَنِي سَالِمُ بْنُ عَبْدِ اللَّهِ، عَنْ أَبِيهِ، . أَنَّ عُمَرَ بْنَ الْخَطَّابِ، بَيْنَا هُوَ يَخْطُبُ النَّاسَ يَوْمَ الْجُمُعَةِ دَخَلَ رَجُلٌ مِنْ أَصْحَابِ رَسُولِ اللَّهِ ﷺ فَنَادَاهُ عُمَرُ أَيَّةُ سَاعَةٍ هَذِهِ فَقَالَ إِنِّي شُغِلْتُ الْيَوْمَ فَلَمْ أَنْقَلِبْ إِلَى أَهْلِي حَتَّى سَمِعْتُ النِّدَاءَ فَلَمْ أَزِدْ عَلَى أَنْ تَوَضَّأْتُ . قَالَ عُمَرُ وَالْوُضُوءَ أَيْضًا وَقَدْ عَلِمْتَ أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَأْمُرُ بِالْغُسْلِ .
