Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet (peace and blessings of Allah be upon him) said: "Whoever calls towards guidance, he will have a reward equal to the reward of all those who follow that guidance, and nothing will be diminished from their rewards. And whoever calls towards misguidance, he will bear a sin equal to the sin of all those who follow that misguidance, and nothing will be diminished from their sins."
