Sayyiduna Abu Bakrah (may Allah be pleased with him) narrates: When the Prophet (peace and blessings be upon him) was besieging the fortress of Ta'if, I let myself down with the help of a rope and came to the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) asked: "How did you come down?" I said: "I let myself down with the help of a rope." The Prophet (peace and blessings be upon him) said: "You are Abu Bakrah (that is, the one with the rope)."
Al-Tabarani recorded it. Its chain contains Abu al-Minhal al-Bakrawi, whom I do not know; the rest of its narrators are thiqat (trustworthy).
