Answer: First, the ḥadith, “Whoever changes his religion, kill him,” is authentic. Al-Bukhārī and others among the scholars of the Sunnah transmitted it with this very wording: “Whoever changes his religion, kill him.” As for reconciling it with the other proofs that were mentioned, praise be to Allah, there is no contradiction.
