Saifuddin Abdullah said such proactive measures were needed to ensure that those platforms were not dominated by those who did not understand Islam and its teachings.
He said with regard to many pertinent issues, the voice of the Muslims was being suppressed.
“We need to stand up, master the subject and lead the debate as now, on many occasions, we are not well-represented when it comes to issues relating to democracy and human rights.
“For example, issues like reproductive health and abortion, our voices are not being heard.
“Therefore, Muslim scientists and activists should participate in dialogues to defend Islam and its teachings,” he told reporters after attending a plenary session on “Preservation of National Identity” in Malaysia's capital.
The event is one of the four plenary sessions held in conjunction with the Kuala Lumpur Summit, which is being attended by delegates from 56 Islamic countries.
Saifuddin said it was also crucial for Muslims living in non-Muslim countries to preserve their identity.
“It is tough for Muslims who live in the non-Muslim world to protect their identity and the situation will be even harder when a Muslim is a migrant or a refugee.”
On a proposed TV channel to combat Islamophobia, he said the initiative by Malaysia, Turkey and Pakistan was already in the pipeline and urged Muslim nations to work together to provide quality content.
