sansaar ki har shay ka itana hi fasaana

Welcome to the forum, I hope you benefit from this forum.

I knew shay meant everything, but I wasn't sure of the exact translation, so I googled it and found an interesting translation:

Shai – Its hindi word derived from Arabic Word – Shain , which means THING..(as in anything, everything..), in hindi it would be Cheez… (not cheese…LOL). Further Shaiyen (in arabic) mean Living thing, Anyway, Shai here means, PERSON.

Coming to – Har Shai Phasana hai – That means Everyone is a story. It doesnt make much of a sense when you translate in english, but thats the way it is.
(Everyone has a story would be the best, but thats not the accurate translation…)
