Do people think that they will be left alone because they say: “We believe,” and will not be tested.
Verily, Allaah knows those who believe, and verily, He knows the hypocrites (i.e. Allaah will test the people with good and hard days to discriminate the good from the wicked, although Allaah knows all that before putting them to test).
O you who believe! Keep your duty to Allaah and fear Him, and speak (always) the truth.
