Believers, stand firm when you meet a band of your enemy and remember God often so that you may have everlasting happiness. 45 And obey Allah and His Messenger, and do not quarrel with one another lest you should lose courage and your power depart. Be steadfast, surely Allah is with those who remain 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 recall when Satan made their works seem fair to them and said: 'None shall overcome you today. and I am your supporter.' But when the two armies faced each other, he turned on his heels, and said: 'Surely I am quit of you for I behold that which you do not. Indeed I fear Allah, and Allah is stern in punishment.' 48
