As Ajibola's name was announced amid 20 finalists, she broke down into "tears of happiness" and also recited Koranic verses, in the beauty pageant that was exclusively meant for the Muslim women. The beauty contest was held in the Indonesian capital, Jakarta.
All the contestants from six countries were covered from head to toe as they were wearing head-scarves, embroidered dresses and stilettos.
The criteria on which they were judged was their knowledge and views on the Islam in the modern world and how well they recited Koranic verses.
After being crowned as the Miss Muslimah, Ajibola said "thanks to almighty Allah" that she had won the contest.
Besides, she also received 25 million rupiah ($2,200) and trips to Mecca and India as prizes.
Ajibola said before the final that the event "was not really about competition". "Were just trying to show the world that Islam is beautiful," she said.
The Muslimah beauty pageant was organised to challenge the idea of beauty put forward by the British-run Miss World pageant.
The winner of the last year's pageant was Indonesian girl Nina Septiani.
The pageant was founded three years ago by Eka Shanti, who lost her job as a TV news anchor for refusing to remove her headscarf. Shanti billed the contest as "Islam's answer to Miss World".
"This year we deliberately held our event just before the Miss World final to show that there are alternative role models for Muslim women," she said.
"But its about more than Miss World. Muslim women are increasingly working in the entertainment industry in a sexually explicit way, and they become role models, which is a concern", she said.
The contest was first held in 2011 and was only open to Indonesians.
The event was hosted by Dewi Sandra, an Indonesian actress and pop star who recently hung up her racy dresses for a headscarf.
More than 500 contestants competed in online rounds to get to the Muslimah World final in Indonesia, one of which involved the contenders comparing stories of how they came to wear the headscarf.
The contest was first held in 2011 under a different name and was only open to Indonesians, Shanti said, but after the media began comparing it to Miss World, it was rebranded as a Muslim alternative to the world-famous pageant.
Because of its popularity, organisers accepted foreign contestants this year for the first time, with Iran, Malaysia, Bangladesh, Brunei, Nigeria and Indonesia represented.
