Raising it here would be more appropriate, since it accords with all the other rational proofs while affirming what the Messengers brought, including the affirmation of Allah’s attributes of perfection—indeed, of His very reality, without which He could not exist. They could therefore have said: “Why could the necessary aggregate, necessary composite, or necessary whole not be necessary by virtue of the necessity of each of its parts, which are necessary in themselves and cannot cease to exist?”
