The converse of a statement is formed by interchanging the hypothesis and the conclusion of the original statement. For example, the converse of the statement "If it is raining, then the ground is wet" is "If the ground is wet, then it is raining."
Contrapositive -> "We have already sent Our messengers with clear evidences and sent down with them the Scripture and the balance that the people may maintain [their affairs] in justice. And We sent down iron, wherein is great military might and benefits for the people, and so that Allah may make evident those who support Him and His messengers unseen. Indeed, Allah is Powerful and Exalted in Might."
