As we approach the blessed nights of destiny, there are many question about these nights and how to designate them. The office of Sayed al-Sistani has answered to this following question from a group of believers as follows:
What is the view of His Eminence in the appointment of Layali al-Qadr? What are the closest possibilities?
The answer was:
In the name of the Almighty, it is most probable that it is one of the two nights (nights of 20th and 22nd of the holy month of Ramadan). And it is likely to be the night of 18th. The believers should perform the special works on these three nights.
