Why do Qatari men grow beards?

Qatari men grow beards because Qataris believe in Islam. According to relevant public information, because growing a beard is a sacred line for Muslim men to follow the prophet, Muslim men in the Middle East all grow beards. Its root cause is water shortage. Because Arab civilization originated in arid areas, there was not enough water to waste on shaving, and there was no electric razor in ancient times, so they used to have beards all over their faces.
