He dismissed the agreement as a "paper agreement" that would not bring security to Saudi Arabia, arguing that Riyadh should change its policies instead .
By August 10, the official tone softened. Foreign Ministry Spokesperson Esmaeil Baghaei told reporters that Tehran saw "no reason to worry that this treaty is against Iran" and called the pact a positive step toward Muslim solidarity. He also framed the agreement as evidence that Middle Eastern nations realize "security is not a commodity that can be purchased from false security brokers" .
The most pointed warning came from Iran's hardline Kayhan newspaper on August 10, which drew a clear red line: any use of the pact against Iran-aligned groups — including Yemen's Houthis — would trigger a "decisive response" on the battlefield .
Iranian state media also framed the agreement in a different light, portraying it as an "alliance against Greater Israel" and a shift away from US-dominated security architecture in the region .
Overall, Iran's official line downplayed the pact as non-threatening, while hardline voices were sharply critical and analysts noted that many in Iran believe the alliance also targets Tehran .

Ankara and Islamabad both clarified in public statements that the pact is not directed at Iran or any specific country.
