When is the Most Exalted Name (Allah) in the Qur’an in the nominative case and (Allāh) in the accusative case, and what are the correct recitation cases for the Most Exalted Name in the Qur’an, with evidence from noble verses?

The majestic word (Allah) is a declinable noun. It is in the nominative case (marfu‘) if it is a subject (mubtada’) or preceded by a nominative agent. It is in the accusative case (mansub) if it is preceded by an accusative agent. Its letter 'lam' is pronounced with a heavy, thick sound (taghliz) if it is preceded by a fatḥah or a ḍammah, and it is pronounced with a light, thin sound (tarqiq) if it is preceded by a kasrah, regardless of whether the kasrah is original or circumstantial.
