لَمْ يَلِدْ وَلَمْ يُولَدْ
He neither begets nor is begotten. (112:3)
Yalid is an active imperfect verb; yūlad is passive. The first negates a relation in which the subject would be a begetter; the second negates a relation in which the subject would be begotten. The two forms close off opposite directions of genealogical attribution.
The wāw joins distinct denials, while the repeated lam grants each its own explicit scope. This is not needless repetition of an identical claim.
