Sayyida Umm Qais bint Mihsan Asadiyyah (may Allah be pleased with her), who is the sister of Sayyiduna ‘Ukkasha bin Mihsan (may Allah be pleased with him) and one of those Muhajir women who pledged allegiance at the blessed hand of the Prophet (peace and blessings be upon him), narrates: I brought my child to the service of the Prophet (peace and blessings be upon him), who did not eat anything yet. The Prophet (peace and blessings be upon him) took him and seated him in his lap. The child urinated on the clothes of the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) took water and sprinkled it on that spot. He did not wash it. Ibn Shihab says: After this, it became customary that the urine of a child is not washed until he is able to eat something. When he starts eating, then his urine is to be washed.
