All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
First of all, the scholars differed in opinion regarding the term "leave" whether it is an explicit word of divorce or is a metaphor of divorce.
As for the term "get out", it is not an explicit wording of divorce, but rather a metaphor that does not lead to divorce without the intention of divorce, according to Ibn Qudaamah and other scholars.
Ibn Qudaamah said in Al-Mughni’ when speaking about the kinds of divorce:
"….and the hidden metaphor, such as leave, go away, taste [the bitterness of separation], swallow [the bitterness of separation], …etc.
One of the conditions for the occurrence of divorce is that he should intend divorce with the metaphor, unless he says it in the event of dispute and anger, according to two different narrations.
However, if such a metaphor is a response to her request for divorce, then our Companions [i.e. the scholars of our school] said that divorce takes place. It is with greater reason that intention is required in regard to terms (expressions) that are frequently used in other than divorce, such as: get out, go, and leave; that divorce does not take place until he [the husband] has intended it.” [End of quote]
Allah Knows best.
