The word Allāh is always written without an ʾalif to spell the ā vowel. This is because the spelling was settled before Arabic spelling started habitually using ʾalif to spell ā. However, in vocalized spelling, a small diacritic ʾalif is added on top of the šaddah to indicate the pronunciation.
One exception may be in the pre-Islamic Zabad inscription, where it ends with an ambiguous sign that may be a lone-standing h with a lengthened start, or may be a non-standard conjoined l-h:-
- الاه : This reading would be Allāh spelled phonetically with ʾalif for the ā.
- الإله : This reading would be Al-ʾilāh = "the god" (an older form, without contraction), by older spelling practice without ʾalif for ā.
