Abu Sa’d, may Allah have mercy on him, narrates that once in the mosque of Damascus, he saw Hazrat Wa’thilah, may Allah be pleased with him, during prayer, spit under his left foot and rub it with his foot. When he finished the prayer, I said to him, “You are a companion of the Prophet (peace be upon him), yet you spit in the mosque?” He replied, “I saw the Prophet (peace be upon him) do the same.”
