It is narrated from Abu Juhaifah Wahb bin Abdullah Suwai (may Allah be pleased with him), he says: I saw the Messenger of Allah (peace and blessings be upon him) at the place of Abtah, he (peace and blessings be upon him) performed two rak'ahs of the Asr prayer there and placed a spear between himself and those passing by, and I saw a few white hairs in the beard under the lower lip of the Prophet (peace and blessings be upon him).
