Believers! If you follow those who deny the Truth, they will drive you back on your heels, and you will turn about, losers. 149 But Allah is your Sponsor. He is the Best of victors. 150 We shall cast terror into the hearts of those who disbelieve, because they joined others in worship with Allah, for which He had sent no authority; their abode will be the Fire and how evil is the abode of the Zalimun (polytheists and wrong-doers). 151 God certainly fulfilled His promise to you when you were fighting the unbelievers, by His permission. Even after We showed you what you wanted, you began to lose courage, started quarreling with each other, and disobeyed God's orders. Some of you want worldly gains and others of you want rewards in the hereafter. Then He let you face defeat in order to test you. However, He forgave you. God is Gracious to the believers. 152 ۞ When ye climbed (the hill) and paid no heed to anyone, while the messenger, in your rear, was calling you (to fight). Therefor He rewarded you grief for (his) grief, that (He might teach) you not to sorrow either for that which ye missed or for that which befell you. Allah is Informed of what ye do. 153 After the sorrows you suffered, He sent you relief and some of you were encompassed by slumber. To some others of you, your lives were so important that you, like ignorant people, began thinking suspiciously of God saying, "Do we have any say in the matter?" (Muhammad), tell them, "All matters belong to God." They try to hide within their souls what they do not reveal to you. They say, "Had we had the matter in our hands, we would not have been killed there." Tell them, "Even if you had stayed in your own homes, your sworn enemies could have attacked you and slain you while you were in your beds. God wanted to test you and purge what existed in your hearts. 154 Behold, as for those of you who turned away [from their duty] on the day when the two hosts met in battle - Satan caused them to stumble only by means of something that they [themselves] had done. But now God has effaced this sin of theirs: verily, God is much-forgiving, forbearing. 155
