Tawoos narrates that the Messenger of Allah (peace be upon him) passed by a man while performing Tawaf of the Ka'bah, who was leading another man around by a rein tied to his nose. The Messenger of Allah (peace be upon him) cut it off and then ordered that man to lead him by hand for Tawaf. He narrates that the Messenger of Allah (peace be upon him) passed by a man while performing Tawaf of the Ka'bah, who had tied another man's hand with a strap, thread, or something else. The Prophet (peace be upon him) cut it off and said: "Lead him by hand for Tawaf."

Tawoos narrates that this narration was reported by Sayyiduna Ibn Abbas from the Prophet Muhammad (peace be upon him). Imam Abu Bakr (may Allah have mercy on him) says that in this hadith there is evidence for the concession of speaking about enjoining good and forbidding evil during Tawaf.
