[Baqarah 2:6] As for those whose fate is disbelief, whether you warn them or do not warn them - it is all one for them; they will not believe. (Because their hearts are sealed - see next verse).
[Baqarah 2:7] Allah has sealed their hearts and their ears, and on their eyes is a covering; and for them is a terrible punishment.
[Baqarah 2:8] And among the people are some * that say, "We believe in Allah and the Last Day **" whereas they are not believers! (* The hypocrites ** the Day of Resurrection)
[Baqarah 2:9] They wish to deceive Allah and the believers; and in fact they deceive none except themselves and they do not have any understanding.
[Baqarah 2:10] In their hearts is a disease, so Allah has increased their disease; and for them is a painful punishment, because of their lies.
[Baqarah 2:11] And when it is said to them, “Do not cause turmoil in the earth”, they say, “We are only peacemakers!”
[Baqarah 2:12] Pay heed! It is they who are mischievous, but they do not have sense.
[Baqarah 2:13] And when it is said to them, "Believe as the others believe", they say, "Shall we believe as the foolish believe?" It is they who are the fools, but they do not know.
[Baqarah 2:14] And when they meet with the believers, they say, "We believe"; and when they are alone with their devils, they say, "We are undoubtedly with you, we were just mocking!"
[Baqarah 2:15] Allah (befitting His Majesty) ridicules them, leaving them to wander blindly in their rebellion.
[Baqarah 2:16] These are the people who purchased error in exchange of guidance - so their bargain did not profit them, and they did not know how to trade.
