Hazrat Abu Hurairah, Allah be pleased with him, narrates that the Holy Prophet, peace and blessings of Allah be upon him, said:
“A person who invites people to the truth gets a reward equal to the reward of all those who accept the truth [at his invitation], while nothing will be subtracted from their rewards. Likewise, a person who entices others to sin carries the burden of all the sins committed at his inducement, while nothing will be subtracted from the punishment of those who commit the sins.”
(Sahih Muslim)
