Abu Hurairah (May Allah be pleased with him) reported:
Messenger of Allah (ﷺ) said, "If anyone calls others to follow right guidance, his reward will be equivalent to those who follow him (in righteousness) without their reward being diminished in any respect, and if anyone invites others to follow error, the sin, will be equivalent to that of the people who follow him (in sinfulness) without their sins being diminished in any respect".[Muslim].
