Sahih al-Bukhari 3990
Narrated Nafi:
Ibn 'Umar was once told that Said bin Zaid bin 'Amr bin Nufail, one of
     the Badr warriors, had fallen ill on a Friday. Ibn 'Umar rode to him 
     late in the forenoon. The time of the Friday prayer approached and Ibn
     'Umar did not take part in the Friday prayer.
حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا لَيْثٌ، عَنْ يَحْيَى، عَنْ نَافِعٍ، أَنَّ ابْنَ عُمَرَ ـ رضى الله عنهما ـ ذُكِرَ لَهُ أَنَّ سَعِيدَ بْنَ زَيْدِ بْنِ عَمْرِو بْنِ نُفَيْلٍ ـ وَكَانَ بَدْرِيًّا ـ مَرِضَ فِي يَوْمِ جُمُعَةٍ فَرَكِبَ إِلَيْهِ بَعْدَ أَنْ تَعَالَى النَّهَارُ وَاقْتَرَبَتِ الْجُمُعَةُ، وَتَرَكَ الْجُمُعَةَ
