Why Scholars think that Hz. Khidr (A.S) is still Alive? What is the story of Hz. Khidr (A.S)?
There is definitive opinion of any scholar that Khidhr Alaihis Salam is still alive. Some do believe that it is possible that he is alive but the truth is only known to Allah. Your correct Aqeedah does not rely on whether Khidhr Alaihis Salam is alive or not.
And Allah knows best.
