Understand the rule
The word Allah is a common and important case in Tajweed. The Lam is heavy when Allah begins recitation or follows a fatha or damma, and light when it follows a kasra, as in بِسْمِ اللَّهِ. The vowel immediately before the word matters when Allah is connected to what precedes it. The heaviness and lightness are heard in the Lam itself and should be practised with the full word in context. This is a memorized case in most curricula, but the sound still needs to be heard and refined with a teacher rather than guessed from a written rule alone.
When does it occur?
It appears whenever the word Allah is recited. At a fresh start it is heavy; in connected recitation, the preceding vowel determines whether the Lam is heavy or light.
Which letters are involved?
How is it pronounced?
Listen for a fuller Lam after fatha or damma and a thinner Lam after kasra; confirm the contrast with a qualified reciter.

Fatha or damma before: heavy Lam. Kasra before: light Lam. The vowel travels into the word and decides.
Practice
Try to identify the trigger first, say the sound slowly, then listen and repeat. Short, accurate practice is more useful than rushing through many examples.

Important Note
Tajweed is best learned through both understanding and listening. Written explanations can help you understand the rules, but correct pronunciation, timing, and articulation are best learned by listening to a qualified reciter or teacher and practicing along with them.
For the best results, combine reading, listening, repetition, and guidance from a qualified Tajweed teacher.
