قَدِيمٌ بِلَا ابْتِدَاءٍ، دَائِمٌ بِلَا انْتِهَاءٍ.
He is without any beginning and remains forever without any end.
Reading the terms: Bilā ibtidāʾ addresses beginninglessness; bilā intihāʾ addresses endlessness. Qadīm and dāʾim are not mere repetitions of one aspect.
Boundary of meaning: A creature’s prolonged or continued existence is not equivalent to the Creator’s beginninglessness. Created survival does not make a being eternal without beginning.
Takeaway: Allah has neither beginning nor end.
