The best news for the faithful is his return to God
…and to Him you shall be brought back. (36:83, al Yasin Sura) The return is to God.
And Allah's is the unseen in the heavens and the earth, and to Him is returned
the whole of the affair; (11:123)
This is mentioned at several places in Quran. For a believer this is the best of good tidings just as it is the worst and most frightening warning for the unbeliever. O Believer! Your return is to the Most Kind and the Most Rewarding Allah. O oppressor! Your return too is to the wrathful and revenging God.
So, O believers! Come with enthusiasm and do your deeds for God, as you are to return only to Him. O oppressors, tyrants, and despots! You also are warned. Repent over your misdeeds and compensate for the past because your return also is to Him. Do not be forgetful of God. But, generally such admonitions do not move a proud person. Arrogance has destroyed him and he is not afraid of anything.
