With the arrival of the Muslim holy month of Ramazan in war-scarred Libya, a group of volunteers work around the clock to restore old or damaged copies of the Quran.

Khaled al-Drebi, one of Libya's best-known restorers of Islam's holy book, is among the artisans who arrive at a Tripoli workshop daily to meet the needs of the influx of customers during Ramazan.

For Muslims, Ramazan is a month of spirituality, where a daily dawn-to-dusk fast is accompanied with prayer and acts of charity -- often translating into a surge in sales of Quran.

"The purchase of new Quran traditionally increases before the month of Ramazan, but this has recently changed in Libya," Drebi told AFP.

For many, tradition has been interrupted by an increase in the cost of Quran, especially "since the state stopped printing" them in Libya, he added.

The North African nation has endured more than a decade of conflict, leaving many of its institutions in disarray and dealing a major blow to the oil-rich country's economy.

"The cost of buying (Quran) has increased, and so the turnout for restoring old Quran has gained unprecedented popularity," Drebi said.

Compared to the cost of a new Quran -- at more than $20 depending on the binding -- Drebi's workshop charges just a few dollars to restore one.

'Indescribable joy'

But cost is not the only factor -- for many, the older copies also have a sentimental value.

"There is a spiritual connection for some customers," Drebi said, adding that many choose to preserve Quran passed on from relatives. "Some say this Quran has the smell of my grandfather or parents."

At the back of the room, Abdel Razzaq al-Aroussi works on sorting through thousands of Quran based on their level of deterioration.

"The restoration of Quran with limited damage takes no more than an hour, but for those that are very damaged, they could require two or more hours," Aroussi said.

They "must be undone, restored and then bound", he said -- a meticulous process that requires a great deal of "time and concentration".

Mabrouk al-Amin, a supervisor at the workshop, said the restoration process "requires a good number of artisans".

"Working with the book of God is very enjoyable and we don't get bored... there is an indescribable joy in this work," he said.

Restorers say they have repaired a staggering half a million Quran since the workshop opened in 2008, and more than 1,500 trainees have graduated from 150 restoration workshops.

Women restorers

In recent years, more and more women have been joining the ranks of the volunteer restorers.

"A large number of women were trained on restoring the holy Quran and today they have their own workshops," Drebi said.

One female restorer, Khadija Mahmoud, has even held training sessions for blind women.

"We would not have been able to think of doing this... were it not for this capable woman," Drebi added.

For Mahmoud, who trains women at a workshop in Zawiya, 45 kilometres (28 miles) west of Tripoli, restoring Quran in a women's workshop allows them to work comfortably and at a faster pace.

She added that the restoration work has given many women a meaningful way to fill their "spare time".

"A large segment of trainees and restorers are retirees," she said. "For them, there is nothing better than spending their spare time in the service of the Quran."
