O believers, when you meet an army, stand firm, and think of God a great deal that you may be blessed with success. 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 Do not be like those who left their homes elated with insolence and showing off to people, barring others from the Path of Allah but Allah encompasses 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
