The lecture slides from the module of Universiti Teknologi Malaysia (UTM), which went viral online, had portrayed Hindus in India as "unclean and dirty" and misrepresented the history of Sikhism.
India had expressed concern over the "negative and incorrect" picture conveyed about Hinduism and Sikhism, following which the varsity had also issued an apology.
UTM vice-chancellor Dr Prof Wahid Omar said the lecturer responsible for the controversial slides has been sacked and his 30-day dismissal notice came into effect yesterday.
Asked why the dismissal was not immediate, Dr Wahid said the procedure had to be done according to the contract, which meant giving the staff a month's notice.

Meanwhile, the youth wing of the country's largest ethnic Indian based political party, the Malaysian Indian Congress (MIC) welcomed the sacking of the lecturer.
"The slides were likely made with an intention to ridicule and downgrade Hinduism and Sikhism," he said in a statement.
Sivarraajh hoped such an incident would not recur, especially by educationists from a university that should place value on learning.
