"Homosexuality is offence under Shariat Law and haram (prohibited) in Islam," Deputy Vice Chancellor of the Darul Uloom Deoband Maulana Abdul Khalik Madrasi said.
Madrasi also asked the government not to repeal section 377 of the Indian Penal Code which criminalises homosexuality.
His objection came a day after Union Law Minister Veerappa Moily said a decision on repealing the section would be taken only after considering concerns of all sections of the society, including religious groups like the church.
Terming gay activities as crime, Maulana Salim Kasmi, Vice-President of the All-India Muslim Personal Law Board, said homosexuality is punishable under Islamic law and section 377 of IPC should not be tampered.
Maulana Mohd Sufiyan Kasmi, an AIMPLB member, and Mufti Zulfikar, President of Uttar Pradesh Imam Organisation have also expressed similar views on the issue.
Kasmi said it would be harmful for the society to legalise gay sex. Buoyed by the news that the Centre is considering repealing the controversial section of the IPC, members of the gay community on Sunday held parades in several cities.
