The Messenger of Allah (peace be upon him) said: 'Whoever introduces a good practice (sunnah) in Islam will have the reward of it and the reward of everyone who acts upon it after him, without diminishing their rewards at all. And whoever introduces a bad practice in Islam will bear its sin and the sin of everyone who acts upon it, without diminishing their sins at all.'
