There was a man from the Ansar (who was a friend of mine). If he was not present in the company of Messenger of Allah ﷺ I used to be present with Messenger of Allah ﷺ, I would tell him what I used to hear from Messenger of Allah ﷺ, and when I was absent from Messenger of Allah ﷺ he used to be present with him, and he would tell me what he used to hear from Messenger of Allah ﷺ .  

البخاري:٧٢٥٦حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ عَنْ يَحْيَى بْنِ سَعِيدٍ عَنْ عُبَيْدِ بْنِ حُنَيْنٍ عَنِ ابْنِ عَبَّاسٍ عَنْ عُمَرَ ؓ قَالَ

وَكَانَ رَجُلٌ مِنَ الأَنْصَارِ إِذَا غَابَ عَنْ رَسُولِ اللَّهِ ﷺ وَشَهِدْتُهُ أَتَيْتُهُ بِمَا يَكُونُ مِنْ رَسُولِ اللَّهِ ﷺ وَإِذَا غِبْتُ عَنْ رَسُولِ اللَّهِ ﷺ وَشَهِدَ أَتَانِي بِمَا يَكُونُ مِنْ رَسُولِ اللَّهِ ﷺ
