حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ أَخْبَرَنَا سُفْيَانُ يَعْنِي ابْنَ حُسَيْنٍ عَنِ الْحَكَمِ عَنْ مُجَاهِدٍ قَالَ كُنَّا مَعَ ابْنِ عُمَرَ فِي سَفَرٍ فَمَرَّ بِمَكَانٍ فَحَادَ عَنْهُ فَسُئِلَ لِمَ فَعَلْتَ فَقَالَ رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَعَلَ هَذَا فَفَعَلْتُ
مسند امام احمد بن حنبل · Hadith 4870
It was narrated that Mujaahid said: We were with Ibn Umar on a journey, and he passed by a place and went around it. He was asked; Why did you do that? He said: I saw the Messenger of Allah (PBUH) do that, so I did it.
