[Machine] Al-Hassan said, "Do not blame me, may Allah have mercy on you. For indeed, the Messenger of Allah ﷺ saw the Banu Umayyah delivering sermons, one after another, on his pulpit, and that displeased him. So, the verse of the Qur'an was revealed: 'Indeed, We have granted you, [O Muhammad], al-Kawthar. So pray to your Lord and sacrifice [to Him alone]. Indeed, your enemy is the one cut off.' And the verse was revealed: 'Indeed, We sent it down during the Night of Decree. And what can make you know what is the Night of Decree? The Night of Decree is better than a thousand months. The angels and the Spirit descend therein by permission of their Lord for every matter. Peace it is until the emergence of dawn.' And the descendants of Umayyah can never equal or decrease [the status of these verses]." This is an authentic narration, and the one who said this to al-Hassan ibn Ali was Sufyan ibn al-Layl, the companion of his father.
