Narrated Ibn `Umar: While `Umar 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. `Umar 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 `Umar said to him, "Did you perform only the ablution although you know that Allah's Messenger (p.b.u.h) used to order us to take a bath (on Fridays)?"

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ أَسْمَاءَ، قَالَ أَخْبَرَنَا جُوَيْرِيَةُ، عَنْ مَالِكٍ، عَنِ الزُّهْرِيِّ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ بْنِ عُمَرَ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ أَنَّ عُمَرَ بْنَ الْخَطَّابِ، بَيْنَمَا هُوَ قَائِمٌ فِي الْخُطْبَةِ يَوْمَ الْجُمُعَةِ إِذْ دَخَلَ رَجُلٌ مِنَ الْمُهَاجِرِينَ الأَوَّلِينَ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم 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 صلى الله عليه وسلم كَانَ يَأْمُرُ بِالْغُسْلِ.
