Al-Qummi indicates in his Tafsir, that the Messenger of Allah (S) once saw in a vision monkeys climbing over his pulpit, and he felt very distressed; thereupon, the chapter of Qadr was revealed to remove his distress. What is the significance of this?
The period of Banu Umayyad's government lasted roughly a thousand months: from 661 to 750 A.D., with the first ruler being Abu Sufyan and the last Mu’awiyah al-Himar. Lailatul Qadr is better than a thousand months.
