Approved answer
Rules of Noon Saakin and Tanween
In order to accurately articulate Noon Saakin and Tanween in conjunction with other letters, Tajweed specifies four essential rules: Izhar, Idgham, Iqlab, and Ikhfaa. The Izhar rule makes the Noon Saakin or Tanween clearly pronounced when it precedes specific throat letters. Conversely, the Idgham rule combines Noon Saakin or Tanween with certain letters, with or without the nasal sound known as ghunna.
