There is no power and no ability except by ALLAH. Logic is not a foundational principle by which I am going to immediately grant carte blanche to judge God's actions without inspecting the metaphysical underpinnings. Therefore the idea of logic and omnipotence being described in that piece is not something that I associate with ALLAH if it contradicts other established principles. And we can get around to inspecting the role of logic once it is properly grounded.
If all of the forces of Earth were to gather against you to benefit you, or to do you harm, it could not occur except by the permission of ALLAH.
But even within the article there is reason to doubt that it actually refers to something substantial, since the entire argument hinges upon how one presumes to interpret "coventant" (as it being something other than a promise of God). God is free of need of our promises for anything. We do not attain to benefitting him, nor attain to harming Him by our actions. One cannot come to a bargain with God. And all affairs that occur in the Earth are by His permission. Therefore all of the "logical" conclusions are doubtful before even questioning the metaphysics of logic and how it might apply to the Divine Perfection.
Regarding contracts, ALLAH - may He be glorified and exalted - says:
2:282 Believers, when you contract a debt for a stated term, put it down in writing; have a scribe write it down with fairness between you. No scribe should refuse to write: let him write as God has taught him, let the debtor dictate, and let him fear God, his Lord, and not diminish [the debt] at all. If the debtor is weak in mind or body, or unable to dictate, then in fairness let his guardian dictate for him. Call in two of your men as witnesses. But if two men cannot be found, then call one man and two women out of those you approve of as witnesses, so that if one of the two women should forget the other can remind her. Let the witnesses not refuse when they are summoned. Do not be disinclined to write down your debts, be they small or large, together with the date of payment. This is more just in the sight of God; it is more reliable as testimony, and more likely to prevent doubts arising between you, unless it be ready merchandise which you give or take from hand to hand, then it will not be held against you for not writing it down. Have witnesses present whenever you trade with one another, and let no harm be done to either scribe or witness, for if you did cause them harm, it would be a crime on your part. Be mindful of God; He teaches you: He has full knowledge of everything. 2:283 If you are on a journey and do not find any literate person, something should be handed over as security. If one of you entrusts another with something, let the trustee restore the pledge to its owner; and let him fear God, his Lord. Do not conceal testimony. If someone does conceal it, in his heart he commits a crime. God knows what you do. 2:284 All that the heavens and the earth contain belongs to God, whether you disclose what is in your minds or keep it hidden. God will bring you to account for it. He will forgive whom He will and punish whom He pleases: He has power over all things.
