As with Al-Noon Al-Saakinah, Al-meem Al-saakinah has it’s own Tajweed rules.

The fourth rule for Al-Noon Al-Saakinah described what idghaam is. Because meem is a letter pronounced using the lips^[1] the rule differs a bit.

Rule one: Idghaam Shafawee (Lip-based Merging or Merging with the use of lips).

For any meem saakinah, when a second meem follows it, Idghaam Shafawee is sounded for two counts, i.e. the time it takes to say the words, “one – two”. The condition here is that the latter meem has a fat-ha, dammah or kasra on it. Note a shaddah on the second meem is drawn as a notice of this rule [i.e. it is not there for shaddah purposes].

Examples of Idghaam Shafawee are as follow:

 قُلُوبِهِمْ مَرَضٌ              لَهُمْ مَا                                                            

lahum maa ____quloobihim maradun

__ أَمْ مَنْ              فَغَشِيَهُمْ مِنَ  _                                               ____

faghashiyahum mina ______ am man

Simple as that. Practice makes perfect.
