Is it true that the faces of disobedient Muslims will be white on the Day of Resurrection, and their bodies will not burn because they belong to the Ummah of Muhammad (peace be upon him)? And did a dialogue take place between Malik and the disobedient that confirms this?

When monotheists are brought out of Hellfire, they are recognized by the mark of prostration (sujud), because the Fire has been forbidden to consume the mark of prostration from the son of Adam. After they are brought out, the water of life will be poured on them, so they will grow like seeds sprout, and they will emerge like pearls, then they will enter Paradise. There is no hadith that mentions a dialogue between Malik and the disobedient.
