Sahih al-Bukhari 3848
Narrated Abu As-Safar:
I heard Ibn `Abbas saying, "O people! Listen to what I say to you, and let me hear whatever you say, 
and don't go (without understanding), and start saying, 'Ibn `Abbas said so-and-so, Ibn `Abbas said soand- 
so, Ibn `Abbas said so-and-so.' He who wants to perform the Tawaf around the Ka`ba should go 
behind Al-Hijr (i.e. a portion of the Ka`ba left out unroofed) and do not call it Al-Hatim, for in the 
pre-Islamic period of ignorance if any man took an oath, he used to throw his whip, shoes or bow in it.
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ الْجُعْفِيُّ، حَدَّثَنَا سُفْيَانُ، أَخْبَرَنَا مُطَرِّفٌ، سَمِعْتُ أَبَا السَّفَرِ، يَقُولُ سَمِعْتُ ابْنَ عَبَّاسٍ ـ رضى الله عنهما ـ يَقُولُ يَا أَيُّهَا النَّاسُ، اسْمَعُوا مِنِّي مَا أَقُولُ لَكُمْ، وَأَسْمِعُونِي مَا تَقُولُونَ، وَلاَ تَذْهَبُوا فَتَقُولُوا قَالَ ابْنُ عَبَّاسٍ، قَالَ ابْنُ عَبَّاسٍ مَنْ طَافَ بِالْبَيْتِ فَلْيَطُفْ مِنْ وَرَاءِ الْحِجْرِ، وَلاَ تَقُولُوا الْحَطِيمُ، فَإِنَّ الرَّجُلَ فِي الْجَاهِلِيَّةِ كَانَ يَحْلِفُ فَيُلْقِي سَوْطَهُ أَوْ نَعْلَهُ أَوْ قَوْسَهُ‏.‏
