The special night is referred to in Sūrat al-Qadr. This chapter of the Quran talks about the revelation of the Quran and the blessings of the Night of Decree (Laylat al-Qadr) which is believed to be one of the last ten nights of Ramadan. It is considered a highly spiritual and blessed night, and it is believed that the reward of worship during this night is better than the worship of a thousand months.
