The word(s) "frontier" appears 1 time(s) in 1 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And prepare against them what force you can and horses tied at the frontier, to frighten thereby the enemy of Allah and your enemy and others besides them, whom you do not know (but) Allah knows them; and whatever thing you will spend in Allah's way, it will be paid back to you fully and you shall not be dealt with unjustly.
