Iqlab

Quick Facts

Level: Essential
Category: Noon and Tanween
When it occurs: It occurs when Noon Sakinah or Tanween is followed by the letter Baa.
Letters involved: ب

Understand the rule

Iqlab means conversion or flipping. When a Noon Sakinah or a tanween is followed by Baa, the Noon sound is converted into a Meem sound that is concealed before Baa with a nasal quality (ghunnah) of about two counts, while the written text stays unchanged. The learner must identify the Noon Sakinah or tanween, detect the Baa trigger, and then recognize the changed sound in a qualified demonstration. The change is a practical sound change, not a rewriting of the text, and it should be heard, imitated, and corrected with a qualified reciter.

When does it occur?

It occurs when Noon Sakinah or Tanween is followed by the letter Baa.

Which letters are involved?

How is it pronounced?

The Noon or tanween is changed to a hidden Meem-like sound before Baa, with ghunnah for approximately two counts; the learner should verify the exact result with a qualified reciter.

Listening guidance Written explanations support recognition. Use an approved recitation and teacher feedback for sound, timing, and articulation.

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.
