CAN I DO QURBAN ON BEHALF OF SOMEONE WHO HAS PASSED ON?

Yes, we can offer Qurban for someone who has passed away.

Many scholars from the Hanafi, Maliki and Hambali Mazhab allow it. In accordance with what the Messenger of Allah (PBUH) did, He sacrificed two goats, the first for himself and the second for His people who have not performed Qurban.

The Mazhab of al-Shafi'i does not allow it.
