Qasem bin Salam said: According to me, it is an ordinary well to which it is not known any (particular) digger, nor owner, but which lies in a valley, and so a human or an animal fall into it. Hence, that is (considered to be) a vain death. It is like a man who is found killed in an open land, by which it is not known for him any killer. Hence, there is no retaliation, nor indemnity for him. As for his saying: « metal is a jubar» they are these metals from which gold and silver are extracted, by which some people would come to dig them up for them for a defined thing [1], and the metal would perhaps collapse on them and kill them. Hence, their blood were shed in vain, because they only worked in return for a reward. As for his saying: «and there shall be one-fifth for rikaz», the people of Iraq and the people of Hijaz have disputed with regards to rikaz. The people of Iraq have said that rikaz refers to metals, all of it, and the people of Hijaz have said that rikaz refers exclusively to buried property among what the sons of Adam have stored before Islam.
