What is Lam Shamsiyyah?

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.

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.
