Narrated Anas:
حَدَّثَنَا مُحَمَّدُ بْنُ عَرْعَرَةَ ، حَدَّثَنَا شُعْبَةُ ، عَنْ يُونُسَ بْنِ عُبَيْدٍ ، عَنْ ثَابِتٍ الْبُنَانِيِّ ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ صَحِبْتُ جَرِيرَ بْنَ عَبْدِ اللَّهِ، فَكَانَ يَخْدُمُنِي. وَهْوَ أَكْبَرُ مِنْ أَنَسٍ قَالَ جَرِيرٌ إِنِّي رَأَيْتُ الأَنْصَارَ يَصْنَعُونَ شَيْئًا لاَ أَجِدُ أَحَدًا مِنْهُمْ إِلاَّ أَكْرَمْتُهُ.
I was in the company of Jabir bin `Abdullah on a journey and he used to serve me though he was older than I. Jarir said, "I saw the Ansar doing a thing (i.e. showing great reverence to the Prophet (ﷺ) ) for which I have vowed that whenever I meet any of them, I will serve him."
