Question

as strange as it sounds i am looking if there is an equivalent to the phrase je ne sais quoi in arabic? or anywhere i would find out?
in english it literally means like "i don't know what it is".. but as je ne sais quoi its sort of abit more special lol ambiguous even. so if there is an equivalent i would greatly appreciate any information
