Please can you tell me the difference between ikhfaa shafawi and Iqlab rules..

Assalamu alaikum

Please can you tell me the difference between ikhfaa shafawi and Iqlab rules.  I am a new learner of Tajweed without a teacher, and am getting a bit confused.  I understand that iqlab is the alteration of noon sakin or tanwin into a mim sakin if the letter ba comes after it.  Ikhfaa shafawi is the concealment of the mim sakin if a ba comes after it.  Yet when I am listening to the Qari recite (Abdullah Basfar), both sounds appear the same.
Jazakallahu Khairun

Answer

Wa alaikum assalaam wa rahmatullahi wa barakatuh,

The only difference between the two, is that in the original letter was a  saakinah that changed into a  saakinah and then followed by a  , and in , the letter is a  saakinah followed by a .   After that, both the steps taken and sound are the same for both.  So you are correct, both  and sound the same. 

Wa iyyaakum wa-l-muslimeen.
