It was narrated from Mundhir bin Jarir that his father said: "The Messenger of Allah said: 'Whoever introduces a good practice that is followed, he will receive its reward and a reward equivalent to that of those who follow it, without that detracting from their reward in their slightest. And whoever introduces a bad practice that is followed, he will receive its sin and a burden of sin equivalent to that of those who follow it, without that detracting from their burden in the slightest.'"

It was narrated that Abu Hurairah said: "A man came to the Prophet, who encouraged the people to give charity to him. A man said: 'I have such and such,' and there was no one left in that gathering who did not give him something in charity, to a greater or lesser extent. The Messenger of Allah said: 'Whoever initiates a good practice that is followed, he will receive a perfect reward for that, and a reward equivalent to that of those who follow it, without that detracting from their reward in the slightest. And whoever introduces a bad practice that is followed, he will receive the complete burden of sin for that, and a burden of sin equivalent to that of those who follow it without that detracting from their burden in the slightest.'"

It was narrated from Anas bin Malik that: The Messenger of Allah said: "Every caller who invites people to misguidance and is followed, will have a burden of sin equal to that of those who follow him, without that detracting from their burden in the slightest. And every caller who invites people to true guidance and is followed, will have a reward equal to that of those who follow him, without that detracting from their reward in the slightest.'"

It was narrated from Abu Hurairah that: The Messenger of Allah said: "Whoever calls people to true guidance, will have a reward equal to that of those who follow him, without that detracting from their reward in the slightest. And whoever calls people to misguidance, will have a (burden of) sin equal to that of those who follow him, without that detracting from their sins in the slightest.'"

It was narrated that Abu Juhaifah said: "The Messenger of Allah said: 'Whoever introduces a good practice that is followed after him, will have a reward for that and the equivalent of their reward, without that detracting from their reward in the slightest. Whoever introduces an evil practice that is followed after him, will bear the burden of sin for that and the equivalent of their burden of sin, without that detracting from their burden in the slightest.'"

It was narrated that Abu Hurairah said: "The Messenger of Allah said: 'There is no caller who invites people to a thing but on the Day of Resurrection he will be made to stand next to that to which he called others, even if he only called one another person.'"
