Though the verse seems to be a little complex, but by some ponder over the expressions, we may easily get the meaning. Here the prophet is addressed saying: ``Do they expect God to appear to them with his angels in HIS glory, and under the shadow of the clouds!? While the matter has already been decreed.'' The last clause of the sentence implies that the punishment of God has been decreed for the obstinate rejectors of faith. the verse then ends in that all matters return to Allah. Matters, here, may mean the raise of the prophet, sending of the HOLY BOOKS, and revealing so many facts that man did not know it. This is just like saying: the rewards and the chastisement of the believers or the mischief makers both return to Allah which means He is the One who decides on these matters.
