It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings of Allah be upon him) said: Whoever establishes a way of misguidance among the people and people follow him, he will bear a sin equal to that of those who follow him, and nothing will be diminished from their sins. And whoever establishes a way of guidance among the people and people follow him, he will receive a reward equal to that of those who follow him, and nothing will be diminished from their rewards.
