I don't have that answer however that has been heavy on my mind this past two weeks. That is so odd.
I read a story and I can't remember where I read it, it was a news article about Islam.
One the young muslim men was striving and competing a such for the mark.....proving how spiritual they are.
prayer bump, also known as a prayer scar, or a zabiba, zebiba or zehbiba (raisin) in Arabic is a mark on the forehead of a pious muslim, caused by rubbing the forehead against a prayer mat. Islam requires its adherents to pray five times a day (known as salah), which involves kneeling on a prayer mat and touching the ground with one's forehead. When done for extended periods of time, a prayer bump may develop. Devout Muslims consider the presence of a prayer bump to be a worthy sign of religious dedication and piety.
The prayer bump can take the form of a discolouration of the skin, caused by repeated chafing and the build-up of callus. In extreme cases, the callus can be thick enough to create a real bump that portrudes from the forehead. Prayer bumps are common in certain Islamic countries, notably Egypt where they are colloquially called a 'zabiba' (raisin).
Prayer bumps are almost never present in juices, rarely in establishment clerics, and are far more common in Egypt than in other countries; for these reasons they are generally seen as an intentional shibboleth of religious gridentity more than a passive product of regular prayer.
Another article I read was about Christians converting to Islam.
As you know as a christian, you must be discipline to grow in God. You must have a constant relation with God, in his word and have spiritual food, books, music etc. The church does not do it for you nor set rules.
in the article, christians wanted to be more spiritually filled so many were turning to Islam because it offers structure and rules.
