Abu Huraira reported God’s messenger as saying, “If anyone summons others to follow right guidance, his reward will be equivalent to those of the people who follow him without their rewards being diminished in any respect on that account; and if anyone summons others to follow error the sin of which he is guilty will be equivalent to those of the people who follow him without their sins’ being diminished in any respect on that account.” Muslim transmitted it.
