Austere religious leader

In Islam what does "Austere religious Scholar or Leader"mean?

Forget what it may mean in your culture.

The Buddhist will try to walk in the ways of Buddha, The Christian in the ways of Jesus, and the Islamist in the ways of their prophet Mohammed. Mohammed is regarded the perfection - rape, brigand, murder, pillage, extermination, pedophilia, necrophiliac etc, the list of perfect behaviors is long.

Along comes Abu Bakr. The austere leader following in the steps of Mohammed, marching to the drums of Islam in globalizing the world into one large Islamic State. With the US attack on his position he fled into a tunnel, and when the search dog found him he was holding his children up as a shield. Rather than submit to capture by the dog and US forces he blew himself and children up with a bomb.

Austere religious Scholar indeed. No not a scholar, but a military leader of  murderous Mohamed sect.

And Trump gets harsh criticism from the media. You will do well to look at the Trump achievements the media is hiding from you: https://www.washingtonexaminer.com/washington-secrets/trumps-list-289-accomplishments-in-just-20-months-relentless-promise-keeping
