Imam Jafar al-Sadiq (ع) said,
“The one who loves us, the People of the Household, and truly loves us in his heart, fountains of wisdom would flow from his tongue, and the faith would be renewed in his heart, and there would be renewed for him the deeds equivalent to those of seventy Prophets, and seventy Truthful ones, and seventy martyrs, and the deeds of seventy worshippers worshipping Allah for seventy years.”
