'Inshallah' to wish something good in the future like >> Inshallah I will get a better degree in the exams 'Mashallah' to say beautiful on something like >> Mashallah this car is so beautiful also FYI they used much more by Muslims.
Thank you everyone. I discovered these words while reading a book. The Kite Runner by Khaled Hosseini.
From what I understand, Inshallah means "If it is God's will," and it's used for when the person is expressing their sincerest hopes that whatever is said will be done, even if it's not guaranteed. Only if God wills so/for it to happen. Does that sound right? :)
