Messenger of Allah ﷺ said, "Anyone of you attending the Friday (prayers) should take a bath."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِذَا جَاءَ أَحَدُكُمُ الْجُمُعَةَ فَلْيَغْتَسِلْ  

While ʿUmar bin Al-Khattab was standing and delivering the sermon on a Friday, one of the companions of the Prophet, who was one of the foremost Muhajirs (emigrants) came. ʿUmar said to him, "What is the time now?" He replied, "I was busy and could not go back to my house till I heard the Adhan. I did not perform more than the ablution." Thereupon ʿUmar said to him, "Did you perform only the ablution although you know that Messenger of Allah ﷺ used to order us to take a bath (on Fridays)?"  

أَنَّ عُمَرَ بْنَ الْخَطَّابِ بَيْنَمَا هُوَ قَائِمٌ فِي الْخُطْبَةِ يَوْمَ الْجُمُعَةِ إِذْ دَخَلَ رَجُلٌ مِنَ الْمُهَاجِرِينَ الأَوَّلِينَ مِنْ أَصْحَابِ النَّبِيِّ ﷺ فَنَادَاهُ عُمَرُ أَيَّةُ سَاعَةٍ هَذِهِ قَالَ إِنِّي شُغِلْتُ فَلَمْ أَنْقَلِبْ إِلَى أَهْلِي حَتَّى سَمِعْتُ التَّأْذِينَ فَلَمْ أَزِدْ أَنْ تَوَضَّأْتُ فَقَالَ وَالْوُضُوءُ أَيْضًا وَقَدْ عَلِمْتَ أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يَأْمُرُ بِالْغُسْلِ  

Messenger of Allah ﷺ said, "The taking of a bath on Friday is compulsory for every male (Muslim) who has attained the age of puberty."  

عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ ؓ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ غُسْلُ يَوْمِ الْجُمُعَةِ وَاجِبٌ عَلَى كُلِّ مُحْتَلِمٍ
