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 Apostle and do not quarrel for then you will be weak in hearts and your power will depart, and be patient; surely Allah is with the patient. 46 Be not as those who went forth from their habitations swaggering boastfully to show off to men, and barring from God's way; and God encompasses the things 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
