assalaam-o-aliakum, if the cow is first stunned, so the cow becomes paralyzed, so its easy to zabiha the cow, is the meat going to be halal or not, fi amanallah

It is Makrooh to stun the animal for the convenience of Zabah. An alternate method should be adopted for the convenience of Zabah. However, if the animal is slaughtered after being stunned, and is alive, the Zabah will be correct and the meat will be Halaal.

and Allah Ta'ala Knows Best
