As for the sunnah, they said: The Messenger, peace and blessings be upon him, said to Unays, may Allah be pleased with him: “Go to this man’s wife, and if she confesses, then stone her.” (1) He did not say, “unless she retracts.” Since he did not state this despite the need for it to be stated, it is known that it is not a condition that she must not retract her confession before the prescribed punishment is carried out on her. For a condition must be fulfilled; otherwise, the ruling cannot be implemented without its fulfillment.
They said: As for your claim that Māʿiz, may Allah be pleased with him, retracted his confession, this is a statement made without knowledge. Māʿiz, may Allah be pleased with him, never retracted his confession. His fleeing does not in any way indicate that he retracted his confession. Whoever claims that this constituted a retraction of his confession has spoken without knowledge. Allah, Exalted is He, has forbidden us to speak without knowledge, as He says:

Yes, Māʿiz’s flight may have been a retraction of his request for the prescribed punishment to be carried out on him. At first, he wanted the prescribed punishment to be carried out on him, but later he wanted it not to be carried out, with his repentance being between him and Allah. This is why the Messenger, peace and blessings be upon him, said: “Why did you not leave him, so that he might repent and Allah would accept his repentance?” (2) This indicates that the ruling of the confession remained in force, for one repents only from zina. The Messenger did not say, “Why did you not leave him, because his confession had been nullified?” Rather, he said: “Why did you not leave him, so that he might repent and Allah would accept his repentance?”
Accordingly, the hadith contains no evidence for what you have claimed; rather, it—
