It was narrated that Hammam bin Harith said:"Jarir bin 'Abdullah urinated, then he performed ablution and wiped over his leather socks. Someone asked him: 'Do you do this?' He said: 'Why shouldn't I? I saw the Messenger of Allah doing this.'" Ibrahim (who narrated it from Hammam) said: "They were pleased by the Hadith of Jarir because he accepted Islam after the revelation of Ma'idah."
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، عَنِ الأَعْمَشِ، عَنْ إِبْرَاهِيمَ، عَنْ هَمَّامِ بْنِ الْحَارِثِ، قَالَ بَالَ جَرِيرُ بْنُ عَبْدِ اللَّهِ ثُمَّ تَوَضَّأَ وَمَسَحَ عَلَى خُفَّيْهِ فَقِيلَ لَهُ أَتَفْعَلُ هَذَا قَالَ وَمَا يَمْنَعُنِي وَقَدْ رَأَيْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ يَفْعَلُهُ . قَالَ إِبْرَاهِيمُ كَانَ يُعْجِبُهُمْ حَدِيثُ جَرِيرٍ لأَنَّ إِسْلاَمَهُ كَانَ بَعْدَ نُزُولِ الْمَائِدَةِ .
