It is narrated from Sayyiduna Jarir (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever initiates a good practice in Islam, he will have its reward and the reward of those who act upon it after him, without their rewards being diminished in the least. Similarly, whoever introduces an evil practice in Islam, he will bear its sin and the sin of those who adopt it after him, without their sins being diminished in the least.
