Article 163

if the object found is worth one Dirham, weighing 12.6 noknods silver, must announce the finding for one year; if the owner of the object does not appear within this time, the finder is entitled to keep it in trust or to make use of it. In the event of his keeping it in trust and being destroyed through no fault of his, he will not be responsible for it. Note: If the finder acquires knowledge at the beginning or before the end of one year that announcement is of no avail, or if he loses the hope of discovering the owner of the object, he will be released of the obligation to make the announcement.
