Question
Assalmualikum
I would like to know which is more correct in Ikhfaa and Iqlaab, to leave the lips slightly open of to close them all the way?

Answer
Wa alaikum assalaam wa rahmatullahi wa barakatuh,
We received this same question from many this last week, for some reason.
The most correct opinion is to close the two lips.  This has been explained in a previous question and answer.
