Anas bin Sulaym al-Hujaymi relates: I said to Sayyiduna Ibn Abbas (may Allah be pleased with them both): What are these reports that have spread among the people, saying: "Whoever performs tawaf of the House has left the state of ihram"? He said: "That is the Sunnah of your Prophet (peace and blessings be upon him), even if it displeases you."
