Is it possible that some people can recognize the Night of Al-Qadr? Is it true that whoever sees its signs and supplicates that his supplication will definitely be answered?

All perfect praise be to Allaah, the Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.

It is true that the supplication made at any of the recommended times is more likely to be fulfilled, Allaah willing. The Night of Al-Qadr is one of these recommended times, along with the last third of the night and the time between the Athaan (call to prayer) and Iqaamah (the immediate call to prayer).

At such times, supplication is most likely to be answered provided there are no impediments present that would prevent the supplication from being answered.

Allaah The Almighty may grant some of His slaves the privilege of seeing one of the signs of this great night. This happened with some of the Companions . In a Hadeeth on the authority of ‘Abdullaah ibn ‘Umar it was mentioned that some of the Companions saw in their sleep that the Night of Al-Qadr is in the last seven nights of Ramadan. Hence, the Prophet, sallallaahu ‘alayhi wa sallam, ordered Muslims to seek this great night in the last seven nights of Ramadan. [Al-Bukhari]

Allaah Knows best.
