This question already has an answer here:
Salam. I wanted to seek some clarification on surah Al Kahf. In verse 79, Al Khidr referred to himself as "I", "As for the ship, it belonged to poor people working at sea. So I intended to cause defect in it as there was after them a king who seized every [good] ship by force." but in verse 80, he used "we", "And as for the boy, his parents were believers, and we feared that he would overburden them by transgression and disbelief."
Can someone share some islamic sources on who the "we" is (besides Al Khidr of course)?
