سُبْحَانَ ٱللَّٰهِ

I.e., "Do they think that it is for them to decide as to who should and who should not be graced with divine revelation?"
If they set themselves to judge Allah, have they anything to show comparable to Allah's Mercy and Power! He has both in infinite measure. Who are they to question the grant of His Mercy and Revelation to His own Chosen One?
