AND [remember, O Prophet, the day] when thou didst set out from thy home at early morn to place the believers in battle array. And God was all-hearing, all-knowing 121 Recall what time two sections of you bethought that they should flag whereas Allah was the Patron of the twain. In Allah, then, let the believers trust. 122 Allah had already given you the victory at Badr, when ye were contemptible. So observe your duty to Allah in order that ye may be thankful. 123 When you said to the believers: Does it not suffice you that your Lord should assist you with three thousand of the angels sent down? 124 If you are steadfast and mindful of God, even though the enemy should suddenly fall upon you, your Lord will help you even with five thousand marked angels. 125 Allah has reminded you of this only as a glad tiding to you and so as to let your hearts be at rest. Help can only come from Allah, the All-Mighty, the All-Wise. 126 That He might cut down a section of the disbelievers or suppress them so that they turn back disappointed. 127 [And] it is in no wise for thee [O Prophet] to decide whether He shall accept their repentance or chastise them - for, behold, they are but wrongdoers, 128 whereas unto God belongs all that is in the heavens and all that is on earth: He forgives whom He wills, and He chastises whom He wills; and God is much-forgiving, a dispenser of grace. 129
