۞ O you who have believed, do not take the Jews and the Christians as allies. They are [in fact] allies of one another. And whoever is an ally to them among you - then indeed, he is [one] of them. Indeed, Allah guides not the wrongdoing people. 51 Those in whose hearts is a disease - thou seest how eagerly they run about amongst them, saying: "We do fear lest a change of fortune bring us disaster." Ah! perhaps Allah will give (thee) victory, or a decision according to His will. Then will they repent of the thoughts which they secretly harboured in their hearts. 52 Then the believers will say, "Are these the men who swore their strongest oaths by God, that they were with you?" Their works will come to nothing and they will lose all. 53 Believers, if any among you renounce the faith, God will replace them by others who love Him and are loved by Him, who will be kind and considerate towards believers and firm and unyielding towards those who deny the truth. They will strive hard for the cause of God and will in no way take to heart the reproaches of the fault finder. Such is God's bounty, which He gives to anyone He wishes. God is bountiful and all-knowing. 54 Behold, your only helper shall be God, and His Apostle, and those who have attained to faith - those that are constant in prayer, and render the purifying dues, and bow down [before God]: 55 As to those who turn (for friendship) to Allah, His Messenger, and the (fellowship of) believers,- it is the fellowship of Allah that must certainly triumph. 56
