Sahih Muslim Book 7, Hadith Number 2867.

Chapter : Saying of people to Ibn ‘Abbas: What to this religious verdict of yours that has engaged the attention of the people?

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 (may peace be upon him), even though you may not approve of it.
