O believers, whensoever you encounter a host, then stand firm, and remember God frequently; haply so you will prosper. 45 And obey Allah and His messenger, and dispute not one with another lest ye falter and your strength depart from you; but be steadfast! Lo! Allah is with the steadfast. 46 And be not like those who came forth from their homes in great exultation and to be seen of men, and (who) turn away from the way of Allah, and Allah comprehends what 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
