Saudi Arabia has launched a national awareness campaign to mobilise people against militants.
The campaign coincides with a counter-terrorism conference taking place in the Saudi capital, Riyadh.
Huge posters have been put up around the city and interviews have been broadcast with ex-militants talking about how they abandoned violence.
Saudi Arabia has witnessed a spate of bombings and shootings blamed on al-Qaeda linked militants since 2003.
The House of Saud is worried about the destabilising influence of militants linked to al-Qaeda.
"People of the world, do you know the truth about Islam? Or do you think it is about bombing things and killing innocent people?"
The slogan in large red letters reads: "Our religion condemns such acts."
Repentant militants talk on television about how happy they are to be on the right path again and a jingle on a programme about Islam asks:
"People of the world, do you know the truth about Islam? Or do you think it is about bombing things and killing innocent people?"
New message
The authorities here are trying to change the mind-set of their people now that they have realised terrorism is a threat not just abroad, but also to Saudi Arabia.
However, what Saudis are being told today about tolerance and respect for non-Muslims is often the opposite of what they have been taught their whole lives.
So it is difficult to tell what impact this campaign is having on the majority of Saudis, let alone hard-core extremists.
Terrorism experts say Saudi Arabia has made substantial progress in clamping down on militant networks.
But some Saudis also complain the House of Saud has yet to tackle extremist sheikhs who still have a real influence on people.
