While ʿUmar (bin Al-Khattab) was delivering the Khutba on a Friday, a man entered (the mosque). ʿUmar asked him, "What has detained you from the prayer?" The man said, "It was only that when I heard the Adhan I performed ablution (for the prayer)." On that ʿUmar said, "Did you not hear the Prophet saying: 'Anyone of you going out for the Jumua prayer should take a bath'?".  

أَنَّ عُمَرَ ؓ بَيْنَمَا هُوَ يَخْطُبُ يَوْمَ الْجُمُعَةِ إِذْ دَخَلَ رَجُلٌ فَقَالَ عُمَرُ لِمَ تَحْتَبِسُونَ عَنِ الصَّلاَةِ فَقَالَ الرَّجُلُ مَا هُوَ إِلاَّ سَمِعْتُ النِّدَاءَ تَوَضَّأْتُ فَقَالَ أَلَمْ تَسْمَعُوا النَّبِيَّ ﷺ قَالَ إِذَا رَاحَ أَحَدُكُمْ إِلَى الْجُمُعَةِ فَلْيَغْتَسِلْ  

Whilst ʿUmar bin al-Khattab was delivering a khutbah, a man came and sat down, ʿUmar said: Why are you coming late to Jumu’ah? The man said: O Ameer al-Muʿmineen, as soon as I heard the call I did wudooʿ, then I came. ʿUmar said: Only wudoo? Didnʿt you hear the Messenger of Allah ﷺ say: ʿWhen one of you goes to Jumu’ah, let him do ghuslʿ? Abu Salamah narrated that Abu Hurairah (...) told him that whilst ‘Umar was delivering the khutbah... and he narrated a similar report.  

الرَّجُلُ يَا أَمِيرَ الْمُؤْمِنِينَ مَا هُوَ إِلَّا أَنْ سَمِعْتُ النِّدَاءَ فَتَوَضَّأْتُ ثُمَّ أَقْبَلْتُ فَقَالَ عُمَرُ وَأَيْضًا! أَلَمْ تَسْمَعُوا رَسُولَ اللهِ ﷺ يَقُولُ إِذَا رَاحَ أَحَدُكُمْ إِلَى الْجُمُعَةِ فَلْيَغْتَسِلْ ؟
