The word(s) "retreat" appears 2 time(s) in 2 verse(s) in Quran in Muhammad Pickthal translation.

(1) But as for those who believe and do good works, for them are the Gardens of retreat - a welcome (in reward) for what they used to do.

(2) And as for those who do evil, their retreat is the Fire. Whenever they desire to issue forth from thence, they are brought back thither. Unto them it is said: Taste the torment of the Fire which ye used to deny.
