I was in the company of Jabir bin ʿAbdullah 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."
صَحِبْتُ جَرِيرَ بْنَ عَبْدِ اللَّهِ فَكَانَ يَخْدُمُنِي وَهْوَ أَكْبَرُ مِنْ أَنَسٍ قَالَ جَرِيرٌ إِنِّي رَأَيْتُ الأَنْصَارَ يَصْنَعُونَ شَيْئًا لاَ أَجِدُ أَحَدًا مِنْهُمْ إِلاَّ أَكْرَمْتُهُ
