In his first major remarks touching on the September 24 hajj stampede, Sheikh Abdulrahman al-Sudais urged people to remember the efforts Saudi Arabia has made to take care of Muslim pilgrims.
"The efforts of the kingdom will not be undermined by the talk of the slanderers that only know to spread lies," Sudais said during weekly prayers at the Grand Mosque, Islam's holiest site.
The mosque was the scene of a construction crane collapse on September 11 which killed at least 108 people, many of them foreign pilgrims, just before hajj.
Data from 29 countries, mostly from official sources, give a total of 1,358 dead in the stampede, far in excess of the Saudi figure of 769 killed.
"It is not the right of anyone or any entity to use these events to blame or spread rumours against the great efforts exerted by the kingdom", Sudais said, according to the official Saudi Press Agency.
Iran, Saudi Arabia's regional rival and the country which reported the highest stampede death toll, has been the most critical.
Iran said 464 of its citizens were killed.
The pilgrimage -- which this year drew about two million faithful -- had been largely incident-free for nine years after safety improvements and billions of dollars spent on infrastructure investment.
