When using classical Arabic is it good / allowed to use quranic "spellings" e.g. Hāmān as هٰمٰن and Aṣ-Ṣalāḧ as الصلَٰوة and Al-Cāfirīn as الكٰفرين. I am not referring to cases where spelling is for qirāʾāt e.g. if im not mistaken in Al-ʿAnbiyāʾ 21:112 it's written 'قٰل' or the case of 'إل‌ياسين'

Ustadh AbdulAziz al-Haqqan

What people usually write may Allah reward you, not how the quran is spelled.
