Believers, if you obey the unbelievers, they will turn you back to disbelief and you will become lost. 149 God is your Guardian and the best Helper. 150 We will throw terror into the hearts of those who disbelieve. For that they have associated with Allah that which He did not send down for a proof. Fire shall be their home, evil indeed is the dwellingplace of the harmdoers. 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 ۞ (Believers remember) when you were fleeing without even glancing to either side even though the Messengers were calling you back, God made you suffer sorrow upon sorrow to make you forget your grief of what you had lost and the injuries you had suffered. God is Well-Aware of what you do. 153 Then He sent down upon you, after grief, security -- a slumber overcoming a party of you; and a party themselves had grieved, thinking of God thoughts that were not true such as the pagans thought, saying, 'Have we any part whatever in the affair?' Say: 'The affair belongs to God entirely.' They were concealing in their hearts that they show not to thee, saying, 'Ah, if we had had a part in the affair, never would we have been slain here.' Say: 'Even if you had been in your houses, those for whom slaying was appointed would have sallied forth unto their last couches'; and that God might try what was in your breasts, and that He might prove what was in your hearts; and God knows the thoughts in the breasts. 154 Those of you who turned away on the day when the two armies met must have been seduced by satan on account of some of what they had earned. But Allah has pardoned them. He is Forgiving and Clement. 155
