As-Salaamu 'Alaykum Warahmatullaah, brothers.

I know that there is elongation in the pronounciation of "Allaah" which is indicated by a dagger alif. My copy of the Qu'ran which is a persian script or Indo-Pak script has the dagger alif. I intend to purchase a new copy.

But I noticed, in the Basmalah of that copy, the dagger alif is not present. I wish to know why that is so and how am I to know if I am to elongate or not in such case.

JazakAllaahu Khayran.
