In Brunei, Nuzul Al-Quran is kept on the 17th of Ramadan, but most other Muslim countries observe it either on the 23rd or 27th of that same month.
|2019||22 May||Wed||Nuzul Al-Quran|
|2020||10 May||Sun||Nuzul Al-Quran|
The occasion for the holiday is the Islamic belief that the Quran, or the first portions of it at least, were revealed to Muhammad sometime during the month of Ramadan. This is why Ramadan is considered the holiest month of the year for Muslims.
Muslims celebrate the day by reciting portions of the Quran, attending mosque, and participating in public prayer. It is a solemn, reflective time in Brunei, as in other Muslim lands.
