It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that once, while performing Tawaf, the Prophet (peace and blessings be upon him) passed by a man who was pulling another man by a rope tied in his nose. The Prophet (peace and blessings be upon him) cut that rope with his hand and said: "Hold his hand and let him perform Tawaf."
