How do you ask how are you in Muslim language?

the language of Qur'an (The Holy Book of Islam) is Arabic

--------

to say "how are you" in Arabic language

"kef halak?" to male or unknown sex or female

"kef halek?" to female

"kef halakom?" to a group

------------------

"kef halakonn?" to a group of females (not used these days)

"kef halakoma" to a group of two person (not used these days)

p.s. this is not the only way to say "how are you" in arabic, for example Egyptians use "Ezayak?" "Ezayek?" and "Ezayakom?" just like how are you and wat's up
