What is the ruling on one who says this phrase: "Allah and Satan are two sides of the same coin," and does this statement constitute disbelief?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: What is the ruling on one who says this phrase, "Allah and Satan are two sides of the same coin"? Does this statement constitute disbelief, or is this speech open to figurative interpretation? And who is responsible for killing him? Is it permissible for any person to kill him?

Answer:
It is not permissible to transmit or mention this speech. This is the ugliest, most severe, and most heinous speech on the face of the earth, equating Allah with Satan. We ask Allah for well-being. There is no doubt in its being disbelief (kufr). It is obligatory for the one in authority, if that is established against him by his confession or by the testimony of witnesses, that the one in authority kill him. It is obligatory for him to do so. Yes.
