Understand the rule
When the definite article al- is attached to a word beginning with a solar letter, the Lam is not pronounced as a clear Lam; it assimilates into the following letter, which then carries shaddah in writing. The fourteen solar (shamsiyyah) letters are: Ta, Tha, Dal, Dhal, Ra, Zay, Sin, Shin, Sad, Dad, emphatic Ta, emphatic Dha, Lam, and Nun. The remaining fourteen letters are lunar (qamariyyah), and with them the Lam is pronounced clearly. In the mushaf the clue is visible: after a solar letter the al- carries no sukoon on the Lam, while after a lunar letter the Lam is written with sukoon. A learner should not rely on the label alone; the sound must be heard from a qualified reciter, since the assimilation is heard in the doubled following letter rather than in a written rule alone.

Sifaat are the qualities of letters: the sound characteristics that help distinguish one letter from another and explain how letter sounds behave in context.

Lam first, then the next letter. A single letter label is not enough to decide the case.
Practice

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.
