And He it is Who has made you successors in the land and raised some of you above others by (various) grades, that He might try you by what He has given you; surely your Lord is quick to requite (evil), and He is most surely the Forgiving, the Merciful.

Do not hold the Messenger's calling (you) among you to be like your calling one to the other; Allah indeed knows those who steal away from among you, concealing themselves; therefore let those beware who go against his order lest a trial afflict them or there befall them a painful chastisement.
