What should one do if one finds a lost child?

The foundling is a child of unknown lineage, and the rulings concerning them are similar to those of lost property (Luqata). Whoever finds them must take them, as a communal obligation (fard kifa'i), and they are considered free. Their possessions, or whatever is found around them, belong to them. The finder (multaqit) should spend on them from that wealth, or from the public treasury (Bayt al-Mal) if they have no wealth. Their religion follows the place where they are found: if they are found in Muslim lands, or in lands where Muslims are numerous, then they are Muslim. Their custody belongs to their trustworthy finder. If the foundling dies or is harmed, their inheritance or blood money (diyah) goes to the public treasury if they have no heir. If a man or woman acknowledges their lineage to the foundling, the foundling is attributed to them, provided that the claim is made individually and its validity is possible. If a group claims them, the one with evidence is given precedence, or the matter is referred to experts in tracing lineage (Qafah).
