Sahih al-Bukhari 387Book 8, Hadith 39
حَدَّثَنَا آدَمُ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنِ الأَعْمَشِ، قَالَ سَمِعْتُ إِبْرَاهِيمَ، يُحَدِّثُ عَنْ هَمَّامِ بْنِ الْحَارِثِ، قَالَ رَأَيْتُ جَرِيرَ بْنَ عَبْدِ اللَّهِ بَالَ ثُمَّ تَوَضَّأَ، وَمَسَحَ عَلَى خُفَّيْهِ، ثُمَّ قَامَ فَصَلَّى، فَسُئِلَ فَقَالَ رَأَيْتُ النَّبِيَّ صلى الله عليه وسلم صَنَعَ مِثْلَ هَذَا. قَالَ إِبْرَاهِيمُ فَكَانَ يُعْجِبُهُمْ، لأَنَّ جَرِيرًا كَانَ مِنْ آخِرِ مَنْ أَسْلَمَ.
Hammam bin Al-Harith said, "I saw Jarir bin `Abdullah urinating. Then he performed ablution and passed his (wet) hands over his Khuffs (socks made from thick fabric or leather), stood up and prayed. He was asked about it. He replied that he had seen the Prophet (ﷺ) doing the same." They approved of this narration as Jarir was one of those who embraced Islam very late.
