Could you please clarify what is meant by khadir about the youth being cut in half by dajjal in this Hadith found in (Sahih Muslim 2938 a) “Abu Ishaq reported that it was said: That person would be Khadir (Allah be pleased with him).” Also is he more eminent than all sahabi in regards to martyrdom

A pious man is what I know, and I don't believe we should be occupying ourselves in who is the person.
