Imam Jafar b. Mohammad al-Sadiq (a.s.) informed: Those who love us and love our lovers without any regard for their own personal benefit, and those who hate our enemies without any personal reasons, will be forgiven on the Day of Judgement, even if their sins are as great as the sand and foam in the sea.
