لَمْ يَلِدْ وَلَمْ يُولَدْ
He neither begot nor was begotten.
«Lam» governs a jussive imperfect verb while denying a past occurrence. «لم يقمْ زيدٌ» denies standing in the relevant past period; it does not on its own determine whether he later stood.
The imperfect form «يقم» does not make the negation future-directed: the governing particle establishes the appropriate temporal reading.
