The second designation is al-Ibn (Son). The source’s characterization connects this term with the first principle and an account of the origin of created existence. The important issue is what is being claimed by the relationship: a term of address, a special status, or an assertion of divinity.
In one usage, “son” can be a metaphor of closeness, love or honor. Such usage does not entail biological generation or intrinsic deity. In another use, divinity is asserted on the basis of that term, which requires independent evidence.
The controlling interpretive rule is that a word with more than one possible usage does not by itself prove the strongest doctrinal conclusion. Its context, customary use and intended referent must first be established.
