Malik related to me from Ibn Shihab from Said ibn al-Musayyabthat Uthman ibn Affan said, "If someone gives something to his smallchild who is not old enough to look after it himself, and in orderthat his gift might be permitted he makes the gift public and has itwitnessed, the gift is permitted, even if the father keeps charge ofit."Malik said, "What is done in our community is that if aman gives his small child some gold or silver and then dies and he hasit in his own keeping, the child has none of it unless the father setit aside in coin or placed it with a man to keep for the son. If hedoes that, it is permitted for the son."
