This dude in the video is crazy, but yea you are right its not used for Prophets.
@Samaalic Era come teach these diaspora kids that only pray on Eid about Islam sxb
You use that on the sahabas, not Kheire.
You are right saaxib, but it is still mainly used for companions of the Prophet Pbuh and great Muslims who have contributed to Islamic history. For example like Imam Shaafici. I doubt any sane Muslim would use those term for Kheyre and put him on the same level as the Saxaaba and the 4 great Imams.
