Sahih Muslim 1244 a
Abu Hassan al-A'raj reported that a person from Bani Hujaim said to Ibn 'Abbas (Allah be pleased with them):
What is this religious verdict of yours which has engaged the attention of the people or which has become a matter of dispute among them that he who circumambulated the House can be free from Ihram? Thereupon he said: That is the Sunnah of your Apostle (ﷺ), even though you may not approve of it.
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالَ ابْنُ الْمُثَنَّى حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، قَالَ حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، قَالَ سَمِعْتُ أَبَا حَسَّانَ الأَعْرَجَ، قَالَ قَالَ رَجُلٌ مِنْ بَنِي الْهُجَيْمِ لاِبْنِ عَبَّاسٍ مَا هَذِهِ الْفُتْيَا الَّتِي قَدْ تَشَغَّفَتْ أَوْ تَشَغَّبَتْ بِالنَّاسِ أَنَّ مَنْ طَافَ بِالْبَيْتِ فَقَدْ حَلَّ فَقَالَ سُنَّةُ نَبِيِّكُمْ صلى الله عليه وسلم وَإِنْ رَغِمْتُمْ ‏.‏
