"Iran has demanded the right to organise... Demonstrations and to have privileges... That would cause chaos during the hajj. This is unacceptable," Foreign Minister Adel al-Jubeir said in a joint press briefing with his British counterpart Philip Hammond.
Tehran said earlier today that Iranians will miss the pilgrimage this year to Islam's holiest sites in Saudi Arabia, and accused Riyadh of "blocking the path to Allah".
Jubeir said Saudi Arabia annually signs a hajj memorandum of understanding with more than 70 countries "to guarantee the security and safety of pilgrims".
"It is very negative if Iran's intention from the start was to manoeuvre and find excuses, in order to prevent its citizens from performing the hajj," he said.
"If it is about measures and procedures, I think we have done more than our duty to meet those needs, but it is the Iranians who have rejected things," he added.
