Most of the times Eid is celebrated early in Pakistan/India than US because of the time difference. If one has given money to someone living in these countries to do qurbani on his/her behalf then is this qurbani valid? As far as I know qurbani is not valid if its done before the Eid prayers. Allah knows the best. Jazak-Allah.
The Qurbaani performed in Pakistan and India after the Eid Salaat there will
be valid even though it may be before the Eid Salaat in the US.
and Allah Ta’ala Knows Best
