Question
As Salam o Alaikum
I have a question regarding ikhfa' in the rules of noon sakinah and tanween. You wrote on your web site that while performing ikhfa' of noon, the tongue should be placed close to the articulation point of the next letter. Our teachers in Pakistan oppose this technique of ikhfa'. They are of the view that the tongue should be brought close to the articulation point of noon itself and not the letter following the noon. They say that if we accept the view that the tongue should be brought close to the articulation point of the next letter, then it is like incomplete idgham (merging) and not ikhfa' and the definition of ikhfa' is that it is between idhar and idgham. Also, it is written in reliable books of tajweed that the tongue has no role in ikhfa'. Can you please clarify and also give a reference to some reliable tajweed book stating that in ikhfa', the tongue should be placed close to the articulation point of the next letter?

Jazak allah

Answer
Wa alaikum assalaam wa rahmatullahi wa barakatuh,
There are different opinions found in different books of tajweed.  His emminence Ash- Sheikh Dr. Ayman Swayd after over 18 years of research came to the conclusion that the placing the tongue near (not at) the articulation of the next letter is the correct technique of making the ikhfa'.  If it were on the the articulation point of the next letter it would sound more like an incomplete idghaam, but because it is near, not on, the letter following the noon is not heard, so there is no idhgaam.  This fits the description of between an idh-haar and idghaam. 

There are indications of the tongue moving close to the next letter during the ikhfa' (not specifically said, but understood) in Ibn Al-Jazarree's book "At-Tamheed" page 161 (the page number maybe not the exact number depending on the printing),  also an indication is found in "At-Tahdeed" p. 115,  also "Tanbeeh Al-Ghaafileen" by As-Safaaqasee, page 104,  and in "Al-Manh Al-Fikriyyah" p 200.  
If one listens to the major shuyookh of tajweed that we have today or in the recent past with strong sanad of ijaazah, such as Sheikh Al-Husary, Sheikh Ayman Swayd, Sheikh Abdullah Basfar, you will find that they all move the tongue close to the next letter during the ikhfa'.  Again it is close to, but not at the letter.
Wa iyyaakum.
