True concealment occupies an intermediate position between clarity and assimilation. Do not form and release a complete independent n, and do not erase its nasal character so that only the next consonant remains. Keep measured nasal resonance, then articulate the next letter correctly.
«أَنْفُسَكُمْ» — concealment before fa, followed by a distinct fa.
«إِنْ كُنْتُمْ» — concealment before kaf, then clear kaf.
«قَوْمٌ ظَلَمُوا» — tanwin before emphatic za (ظ), then articulate that emphatic consonant.
Some concealment letters, such as qaf, sad, dad, ta and za, are heavy. Prepare the resonance appropriately for the next consonant without restoring a separate clearly released nun. This transition requires careful listening and correction.
