As-Sayyid ar-Radi says: Instead of "nassa'l-hiqaq "the combination "nassa'l-haqa'iq" has also been related. "nass" means the last end of things or their remotest limit, such as "an-nassi fi's sayr" means the maximum a beast can walk. Or you say "nasastu'r-rajula 'ani'l-amri" when you have questioned a man to the extreme to make him utter all he has. Thus, "nassu'l-haqa'iq" means prudence because it is the last limit of childhood and is the time when a child crosses childhood into majority, and this is a very eloquent reference to the point, and strange too. Amir al-mu'minin intends to say: When girls reach this stage their relations on father's side have a better right than their mother, provided they are those with whom marriage is prohibited like brothers and uncles, to arrange for their marriages if they so desire. "al-hiqaq" also means the quarrelling of the mother with a girl's paternal relations. This quarrel is that everyone of them says he has a better 'right for her. That is why it is said "haqatuhu hiqaqan" on the lines of "jadaltuhu jidalan". It has also been said that "nassu'l-hiqaq" means acquiring understanding and this is prudence, because Amir al-mu'minin refers to the stage when rights and duties become applicable. The person who has related the word as "haqa'iq" intends to signify the plural of "haqiqah" (reality).
