LessonsRefining Qualities and the Detailed Rules of Lam and RaQuiz

When the immediately preceding sound has kasrah, the lam of Allah’s name is pronounced lightly (with tarqiq). The sanctity of the name does not itself require heavy lam in every setting; the contextual phonetic rule determines the pronunciation.

«بِسْمِ اللَّهِ» — kasrah before the lam makes it light.
«بِاللَّهِ» — the preceding kasrah likewise requires light lam.

Contrast: In «رَسُولُ اللَّهِ», the preceding dammah calls for a heavy lam. In «لِلَّهِ», the kasrah leads to light lam. These are distinct, correct realizations of the same letter.
