There is divine wisdom and mercy why Allah s.w.t. does not reveal which night is Laylatul Qadr. So in these last remaining nights of Ramadhan, let us not nitpick which night to stay up for ibadah. Ibn ul-Qayyim (rahimahullah) said:
“If Laylat ul-Qadr was 1 night in a year,
I would’ve prayed the full year so that I catch it.
What of (only) 10 nights?”
