Vaqyaat or vaqya means an incident or an occurrence.

Here is a beautiful dialogue from the popular Pakistani TV show Zindagi Gulzar Hai, that conveys a powerful thought and uses this lafz:

“zindagi naam hai namumkinaat ka, ittefaqat ka, vaqyaat ka aur unpar hamara koi ikhtiyaar nahin hota.”

Life is all about impossibilities, co-incidences and happenings that we never seem to have any control over.

And here is a couplet by Nazeer Banarasi with this Urdu lafz –

mujhe gham nahin hai is kaa ki badal gayaa zamaanaa
merii zindagii ke maalik kahiin tum badal na jaanaa

mere paas vaqt thodaa, mere vaaqyaat lambe
kahaan sar-guzasht apani, na suno meraa fasaanaa

I am not sorrowful that the world may have changed,
O controller of my life, I hope you don’t change
I have less time, but so many incidents (to go through)
The account of my happenings is in a different realm, do not hear my story
