Translation:

13. `And as for us since we have listened to the Guidance we have accepted it: and any who believes in his Lord has no fear either of a short (account) or of any injustice.

Notes (Tafseer)

5737. Possibly, from this world's standards, it may be that a believer suffers for his Faith. He may be laughed at, persecuted, and actually hurt, "in mind, body, or estate". But he is not perturbed. He takes it all cheerfully, because he knows that when his full account is made up-real gain against apparent loss,-he is a gainer rather than a loser. And his Faith tells him that Allah is a just God, and will never allow him to suffer any injustice, or permit the account of his merit to appear one whit shorter than it is.
