(51) And put thy trust in Allah, and enough is Allah as a disposer of affairs.

(54) If indeed thou ask them who it is that created the heavens and the earth, they would be sure to say, "Allah". Say: "See ye then? the things that ye invoke besides Allah,- can they, if Allah wills some Penalty for me, remove His Penalty?- Or if He wills some Grace for me, can they keep back his Grace?" Say: "Sufficient is Allah for me! In Him trust those who put their trust."

(55) Whatever it be wherein ye differ, the decision thereof is with Allah: such is Allah my Lord: In Him I trust, and to Him I turn.

(56) Whatever ye are given (here) is (but) a convenience of this life: but that which is with Allah is better and more lasting: (it is) for those who believe and put their trust in their Lord:

(59) There is for you an excellent example (to follow) in Abraham and those with him, when they said to their people: "We are clear of you and of whatever ye worship besides Allah: we have rejected you, and there has arisen, between us and you, enmity and hatred for ever,- unless ye believe in Allah and Him alone": But not when Abraham said to his father: "I will pray for forgiveness for thee, though I have no power (to get) aught on thy behalf from Allah." (They prayed): "Our Lord! in Thee do we trust, and to Thee do we turn in repentance: to Thee is (our) Final Goal.

(60) Allah! There is no god but He: and on Allah, therefore, let the Believers put their trust.
