Is the Dajjal alive, and is al-Khidr (peace be upon him) alive?

Question:
We have heard from you, please, Honorable Shaykh. This questioner asks: Is the Dajjal alive? And is al-Khidr (peace be upon him) alive? And what is the relation of that to the hadith of the Prophet (peace and blessings be upon him) that at the head of every hundred years, in the days he (peace and blessings be upon him) specified, no one who is on the earth in that night will remain?

Answer:
Yes. As for al-Khidr, he is dead. The one who says he is alive is wrong; he is not alive, he is dead. Because Allah (Glorified and Exalted is He) says: And if al-Khidr were alive, he would have come to the Prophet (peace and blessings be upon him), because the Messenger (peace and blessings be upon him) was sent to all people. So if he were alive, he would have come to the Prophet (peace and blessings be upon him). So al-Khidr is dead, and what they believe, that he is alive, is a myth.
As for the Dajjal, Allah knows best. Allah knows best. In the hadith of , he is alive, and that he is in a specific place. It came in the hadith that Allah knows best.
As for the hadith of the Messenger (peace and blessings be upon him) that no one remains alive. It means that lifespans generally do not exceed one hundred years. Generally. Generally, a person does not live more than one hundred years. Most people do not live to reach one hundred. And if there are rare exceptions, there is no ruling for the rare; the ruling is for the general case. Yes.
