Believers, when you meet an army stand firm and remember Allah abundantly, in order that you are prosperous. 45 And obey God, and His Messenger, and do not quarrel together, and so lose heart, and your power depart; and be patient; surely God is with the patient. 46 Do not be like those who marched out boastfully to show off their strength to people and hinder people from the way of God. God encompasses everyone's activities. 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
