"Those who kill weak and punish innocent must question themselves as Justice Katju made the statement at a time when he was going to attend a seminar at the Benaras Hindu University," Khan said in a statement issued here.
"None dared to oppose Justice Katju. This happened because the person talking about consuming cow meat and supporting it was not a poor Muslim," he said.
Taking a dig at those calling for prevention of cow slaughter, Khan said "it was their responsibility to see that from now onwards the price of beef is not written in the menu of any five-star hotel".
"Not only dairy products, medicines, purses, belts and shoes should be taken off the market. Those who are not ready to remove these items must be considered guilty of cow slaughter and punished accordingly," he said.
