Question
Please what is ghunnah muraqqaqah
Answer
Muraqqaqah means light, not having tafkheem (not heavy).  When there is an ikhfa' of the saakinah or tanween, we get our mouth ready to say the following letter which caused the ikhfa'.  If the following letter has tafkheem, then we pronounce the ghunnah of the ikhfa' with tafkheem (raise the posterior portion of the tongue up and focus the sound to the roof of the mouth).  If the following letter is one which does not have tafkheem, we make the ghunnah light and do not  raise the posterior portion of our tongue up and do not focus the sound to the roof of the mouth.
