Believers, if you obey those who disbelieve they will turn you upon your heels and you will turn to be losers. 149 Nay, Allah is your Maula (Patron, Lord, Helper and Protector, etc.), and He is the Best of helpers. 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 ۞ And recall what time ye were running off and would not look back on any one, albeit the apostle in your rear was calling unto you. Wherefore He caused sorrow to overtake you for sorrow, that ye might not grieve for that which ye might lose nor for that which might befall you. And Allah is Aware of that which ye work. 153 Then, after sorrow, He sent down unto you a security - slumber coming over a section of you; while another section, concerned about themselves, bethought of Allah unjustly: the thought of paganism. They said: have we aught at all of the affair? Say thou: the affair is wholly Allah's. They hide within themselves that which they disclose not unto thee, saying: had we aught of the affair, we would not have been slain here. Say thou: had ye stayed in your houses, even then those decreed to be slain would surely have gone forth to their places of slaughter; and this happened in order that he might prove that which was in your breasts, and purge that which was in your hearts; and Allah is Knower of that which is in the breasts. 154 Those of you who turned away on the day the two hosts met [in battle] were made to slip by Satan on account of some of their deeds. But God has pardoned them: God is forgiving and forbearing. 155
