During the Question Hour, Khan pointed towards Som and termed him as "beef mafia" questioning his alleged links with slaughter houses.
Som, MLA from Sardhana, said if Azam had any proof, he should table it in the House.
Khan said he had proof of what he said and advised Som to "take a lesson from what happened in a university", without naming Jawaharlal Nehru University (JNU).
Speaker Mata Prasad Pandey later intervened to cool the frayed tempers.
