The ن that is ساكنة is free from any vowels or حركات . It remains still in written form and pronunciation, when stopping or continuing – in recitation. It occurs in nouns, verbs, in the middle and end of words, and in prepositions only in the end such as أن – عن – منThere is a sign for it, but it not always apparent : ْتنوين is an extra ن found in the end of nouns, when continuing to the next word in recitation, it is left out if you stop at the word.It can have two dammas, two kasras, or two fat-has
The letter following the ن or تنوين tells us how to pronounce it, and there are four main rules with regards to it : إظهار – إخفاء – إدغام – إقلاب
linguistically means clear, or obvious.In tajweed, it means pronouncing the letter completely & clearly from its articulation point without a ghunnah – nazalization on the letter.There are six letters – throat letters (ء – هـ – ع – ح – غ – خ ) – that, if preceded by a ن sakinah or تنوين the ن is pronounced clearly.It is pronounced clearly whether it is within one word or between two words. The tanween only occurs in the end however.Examples:
من أي شيء , ينأونمنهم, من هاد , قومٍ هادأنعمت, من عمل , سميع عليم وانحر , فمن حاجك , عليم حكيم
من غفور رحيم
ورب غفور , المنخنقة , من خلاف
Note: Noon has a sukoon sign showing in quran at places of idhaar.
