Jami` at-Tirmidhi Book 47, Hadith 401
“The Prophet was performing Salat when Abu Jahl came to him and said: ‘Have I not forbidden you from this? Have I not forbidden you from this? Have I not forbidden you from this?’ The Prophet turned and scolded him. So Abu Jahl said: ‘You know that no one has more to call for assistance than me.’ So Allah, Blessed is He and Most High, revealed: Then let him call upon his council. We will call out the guards of Hell.” So Ibn Abbas said: “By Allah, if he had called his council, then the guards of Hell would have seized him.”
We will call on the guards of Hell. He said: “Abu Jahl said: ‘If I see Muhammad praying, then I shall stomp upon his neck.’ So the Prophet said: ‘If he does, he will be visibly seized by the angels.’”
“A man stood up in front of Al-Hasan bin Ali, after he pledged to Mu’awiyah, so he said: ‘You have made fools of the believers.’ – or: ‘O you who has made fools of the believers’ – So he said: ‘Do not scold me so, may Allah have mercy upon you, for indeed the Prophet had a dream in which he saw Banu Umayyah upon his Minbar. That distressed him, so (the following) was revealed: Verily We have granted you Al-Kauthar (O Muhammad) meaning a river in Paradise, and (the following) was revealed: ‘Verily We have sent it down on the Night of Al-Qadr. And what will make you know what the Night of Al-Qadr is? The Night of Al-Qadr is better than a thousand months, in which Banu Umayyah rules after you O Muhammad.” Al-Qasim said: “So we counted them, and found that they were one-thousand months, not a day more nor less.”
