Abu Hassan reported,

A man from the tribe of Banu Hujaym said to Ibn Abbas, "What is this legal opinion of yours that has spread widely among the people, that whoever performs tawaf around the House has come out of his ihram?"Ibn Abbas replied, "It is the practice of your Prophet, even if you find it distasteful."
