# Common Mistakes in Applying the Rules of Noon Sakinah and Tanween

<div class="whiteboard-box">- ❌ **Most common error:** stretching the ghunnah on the clarified Nūn (with throat letters).
- ❌ **Ikhfāʾ:** the tongue tip touching the Nūn’s point instead of preparing for the next letter.
- ❌ **Iqlāb:** full lip closure, making it a clear Mīm.
- ❌ **Idghām:** pronouncing the Nūn before the merged letter, or dropping the ghunnah in *yanmū*.
- ✅ One cure: record your voice, compare with a skilled reciter, and get a teacher’s correction.

</div>Why a Whole Article on Mistakes?
--------------------------------

From correcting hundreds of recitations at **Iqraa Irtaqii Academy**, we found that 90% of errors in [the rulings of Nūn Sākinah and Tanwīn](/en/blogs/tajweed-rules-idgham-importance) repeat in just five forms. Knowing them in advance saves months of correction.

1. Iẓhār Errors
---------------

- **Stretching the ghunnah:** saying “min-n āmana” with a long ghunnah. Correct: the Nūn is clear and short, cut off from the next letter without a pause.
- **Qalqalah:** bouncing the silent Nūn. The Nūn is not a qalqalah letter.

2. Ikhfāʾ Errors
----------------

- **Touching the Nūn’s point:** it becomes Iẓhār. Correct: the tongue prepares directly for the next letter’s point.
- **Dropping or shortening the ghunnah:** it is two full counts.
- **Ignoring tafkhīm:** the ghunnah with (ص ض ط ظ ق) is heavy.

3. Iqlāb and Idghām Errors
--------------------------

<table><tr><th>Ruling</th><th>Error</th><th>Correct</th></tr><tr><td>Iqlāb</td><td>closing the lips → clear Mīm</td><td>lips brought close, ghunnah two counts</td></tr><tr><td>Iqlāb</td><td>pronouncing Nūn then Bāʾ</td><td>turn the Nūn into a hidden Mīm</td></tr><tr><td>Idghām with ghunnah</td><td>pronouncing Nūn before *yanmū*</td><td>stress the second letter with ghunnah</td></tr><tr><td>Idghām without ghunnah</td><td>a trace of ghunnah with (ل ر)</td><td>Nūn and ghunnah fully gone</td></tr><tr><td>Idghām</td><td>merging the Nūn within one word (*ad-dunyā*)</td><td>absolute Iẓhār</td></tr></table>

A Practical Correction Plan
---------------------------

1. Record yourself reading a page containing all four rulings.
2. Compare it, sentence by sentence, with a skilled reciter (same narration).
3. Mark the error spots and repeat them 10 times correctly.
4. Present it to a certified teacher once a week until it holds.
