O believers, whensoever you encounter a host, then stand firm, and remember God frequently; haply so you will prosper. 45 Obey God and His Apostle, and do not disagree among yourselves or you will be unmanned and lose courage. Persevere, for God is with those who endure. 46 Be not as those who came forth from their dwellings boastfully and to be seen of men, and debar (men) from the way of Allah, while Allah is surrounding all they do. 47 And when the Shaitan made their works fair seeming to them, and said: No one can overcome you this day, and surely I am your protector: but when the two parties came in sight of each other he turned upon his heels, and said: Surely I am clear of you, surely I see what you do not see, surely I fear Allah; and Allah is severe in requiting (evil). 48
