"Islam is the solution for the problems" of Muslims, he said in a speech before the prayer began, warning the faithful of "a media and cultural invasion that seeks to weaken (their) faith." He urged Muslims to solve their problems "without interference from their enemies," condemning those who want to "provoke hostility between you and your leaders."
"Things are going well and according to plans," interior ministry spokesman General Mansur al-Turki told AFP. Many went on buses, while others set off on foot from Mina, a tent-village that comes to life only during the five-day pilgrimage.
Others took the Mashair Railway, also known as the Makkah Metro, to go to Mount Arafat and its surrounding plains, where the Holy Prophet (PBUH) is believed to have delivered his final sermon. The Chinese-built railway is operating for the first time this year at its full capacity of 72,000 people per hour to ease congestion and prevent stampedes in which hundreds have been killed in past years.
The dual-track light railway connects the three holy sites of Mina, Muzdalifah and Mount Arafat - areas that see a massive influx of pilgrims during the hajj. After sunset, pilgrims swarmed to Muzdalifah, half way between Mount Arafat and Mina, to spend the night.
On Sunday, they return to Mina after dawn prayers for the first stage of the symbolic "stoning of the devil" and to make the ritual sacrifice of an animal, usually a lamb with the beginning of Eid al-Azha, or the Feast of Sacrifice. On the remaining three days of the hajj, the pilgrims continue the ritual stoning before performing the circumambulation of the Kaaba in Makkah and then heading home.
However, the gathering in the plains around Mount Arafat symbolises the climax of the hajj. The hajj is one of the five pillars of Islam and must be performed at least once in a lifetime by all those who are able to make the journey, and it is a dream that can take years to come true. Mukhtar al-Rahman, who is more than 100 years of age, told AFP that "this is the dream of my life which took a century to come true."
"The crowds have tired me and as you can see I can't stand properly because of the huge crowds flooding" into the area, the elderly Bengali said panting as he looked for a small chair to sit on. Meanwhile, Indonesian Noor Laila said: "I'm so happy to have set foot on Arafat's sacred soil."
"I want to wash away all my sins and ask God to forgive my mistakes. This is the first time I come to hajj and I hope it won't be the last," said the 36-year-old. Malaysian Abdullah Wali al-Deen, 45, said he had been working for years for this day. "I came here with my family after we managed to save enough money," he said.
"Everyone in here is equal. There are no differences between various nationalities. This is the religion of peace, love and brotherhood." More than 1.83 million pilgrims have arrived in the kingdom from abroad, marking a 1.5 percent increase from last year, said Makkah governor Prince Khaled al-Faisal. Several hundred thousand Saudis and foreign residents in the kingdom were also granted permits to join them.
Coping with the world's largest annual human assembly poses a security headache for Saudi Arabia - guardian of the two holiest Muslim shrines in the cities of Makkah and Medina, the birth places of Islam. To help prevent chaos, the authorities have numbered buses and tents in Mina and Arafat according to the countries from which the pilgrims have come. For the first time this year, the hajj is being streamed live on video-sharing website YouTube in co-operation with the Saudi government. The stream can bee seen at youtube.com/hajjlive.
