Final answer:
When reciting Al-Quran Al-Kareem, if we encounter a Noon Sakinah or Tanween, we will choose the rule to apply according to the letter that follows it.
Step-by-step explanation:
In the recitation of the Quran, the rules for pronunciation of Noon Sakinah (نون ساكنة) or Tanween (تنوين) are determined by the letter that immediately follows them.
There are two possible rules: Ikhfa (اخفاء) and Idgham (اضغام). Ikhfa is applied when Noon Sakinah or Tanween is followed by one of the letters of Ikhfa (ت ث د ذ ر ز س ش ص ض). In Ikhfa, the sound of Noon is somewhat concealed. On the other hand, Idgham is applied when Noon Sakinah or Tanween is followed by one of the letters of Idgham (ج ب ك ق غ).
In Idgham, the sound of Noon is merged or assimilated with the following consonant, creating a smoother transition. The choice between Ikhfa and Idgham is determined by the specific letter following Noon Sakinah or Tanween, and understanding these rules is essential for correct Quranic recitation.
