حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ سِمَاكٍ سَمِعْتُ ابْنَ عُمَرَ يَقُولُ إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ صَلَّى فِي الْبَيْتِ وَسَيَأْتِي مَنْ يَنْهَاكُمْ عَنْهُ فَتَسْمَعُونَ مِنْهُ قَالَ يَعْنِي ابْنَ عَبَّاسٍ قَالَ وَكَانَ ابْنُ عَبَّاسٍ جَالِسًا قَرِيبًا مِنْهُ
مسند امام احمد بن حنبل · Hadith 5547
It was narrated from Simaak: I heard Ibn 'Umar say: The Messenger of Allah prayed inside the Ka'bah, but there will come one who will tell you not to do that, and you will listen to him He (the narrator) said: He was referring to Ibn 'Abbaas. And Ibn Abbaas was sitting near him.
