INSHALLAH
Etymology
Interjection
inshallah
God willing; Deo volente; expressing the speaker’s wish for a given future event to occur, especially in a Muslim country or Islamic context.
Usage notes
• In many contexts, including military slang, the expression is sarcastic, suggesting that the speaker has no interest in making the future event occur (thus, it will only occur if God steps in and wills it).
• In Arab countries inshallah is often added to any sentence in the future tense. It is to show that the future event is not assured and if God's will steps in, it will not happen. I wish the event happens, but I don't have it all in my hands and unpredictable can happen. I wish it happens, but if it's not God's will, it will not happen.
