[Hence,] O you who have attained to faith, when you meet a host in battle, be firm, and remember God often; so that you might attain to a happy state! 45 Obey God and His Messenger. Do not quarrel with each other lest you fail or lose honor. Exercise patience; God is with those who have patience. 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 what time the Satan made their works fair-seeming unto them and said: there is none of mankind to overcome you today, and verily I am your neighbour. Then when the two parties faced each other, he turned on his heels, and said: verily I am quit of you, verily I behold that which ye behold not; verily I fear Allah: and Allah is severe in retribution. 48
