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 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 And be not like those [unbelievers] who went forth from their homelands full of self-conceit and a desire to be seen and praised by men for they were trying to turn others away from the path of God - the while God encompassed all their doings [with His might]. 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
