Narrated Ghailan bin Jarir:

We used to visit Anas bin Malik and he used to talk to us about the Ansar, and used to say to me: "Your people did so-and-so on such-and-such a day, and your people did so-and-so on such-and-such a day."

حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا مَهْدِيٌّ، قَالَ غَيْلاَنُ بْنُ جَرِيرٍ كُنَّا نَأْتِي أَنَسَ بْنَ مَالِكٍ فَيُحَدِّثُنَا عَنِ الأَنْصَارِ،، وَكَانَ، يَقُولُ لِي فَعَلَ قَوْمُكَ كَذَا وَكَذَا يَوْمَ كَذَا وَكَذَا، وَفَعَلَ قَوْمُكَ كَذَا وَكَذَا يَوْمَ كَذَا وَكَذَا‏.‏
