Pilgrims descend on Mecca for 'smart hajj'

Two million Muslims gather in Saudi Arabia this week for the hajj as the annual pilgrimage becomes increasingly hi-tech with apps to help the faithful navigate Islam's holiest sites.

This year the hajj comes with the ultra-conservative kingdom witnessing an unprecedented pace of change, finally ending a ban on women driving while remaining firm in the face of any dissent.

One of the five pillars of the world's fastest-growing religion, the hajj is expected to draw two million people from around the globe this year.

By yesterday, more than 1.6 million people had already arrived in Saudi Arabia for the pilgrimage, which runs from Sunday to Friday.

Thousands could be seen arriving in Mecca, with groups from different countries wearing distinct colours to set them apart.

Some pilgrims pushed their elderly relatives on wheelchairs while others stopped to call family members back home on video chat or buy ice cream as temperatures soared above 40 degrees Celsius (104 Fahrenheit).

For many, it is their first time away from home.

Every Muslim is required to complete the hajj at least once in their lifetime if they have the means to do so.

Many were visibly moved to be so close to Islam's holiest site -- the Kaaba, a black masonry cube in the centre of Mecca's Grand Mosque.

"I feel as light as a feather," said Senegalese Fame Diouf, who travelled from Amsterdam. Laughing, she recounted the story of how she couldn't stop crying near the Kaaba.

"This was my dream from childhood," said Raja Amjad Hussein, who made the trip to Mecca from Pakistan.

"I can't explain. I have no words," the 40-year-old told AFP. "For many Muslims this is the big, the biggest, dream of life, to see Kaaba and pray for yourself and the whole Muslim nation."
