Abdullah bin Ma'qil bin Muqarrin (may Allah have mercy on him) said: In this same incident, a Bedouin prayed with the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said: "Take up the soil on which he urinated and throw it away, then pour water over that place."
Abu Dawud said: It is mursal; Ibn Ma'qil did not meet the Prophet (peace and blessings be upon him). This has also been narrated in the hadith of Sayyiduna Ibn Mas'ud (may Allah be pleased with him), but it is not sahih (authentic).
