What is the word, “makruh”.

[Steve Van Doorn]

makruh (reprehensible) the Imam or other authority figure is required to inform you that you're not conforming to the Dawah (preaching of Islam.)

Once the person is told and no action was taken then it can be considered Haraam.

There isn't a Muslim alive that lives under Darul-Islam out side ISIS territory. but this is what ALL Muslims are required to achieve. The most common makruh i see nearly all muslims male's do is wear western pants.
This is as bad as a woman without any modesty (Hijab.) which is also makruh.

Oh I should point out

i said, " this is what ALL Muslims are required to achieve."

This includes you. you're a Muslim if you didn't know that. Qur'an 30:30 says everyone is born a Muslim.
All non-mulsims that become Muslim revert back to the teachings of Islam. They where Muslim apostates or Kafirs(living under Darul-Islam.) Not living under darul-Islam they're Harbi Kafirs. (warmongering) Kafirs.
