Hello
what kind of translation are you looking for? Do you mean that you want to understand the meaning?
If yes then :
It's impossible that things dont change >>
دوام الحال من المحال
And also this will finish >>
وهذا ايضاً سوف ينتهي
The longest day will have an end >>
أطول الأيام له نهاية
Else, let me know !
These sentences are in Classical Arabic, wich we (Native speakers/ Advanced learners) understand in the same way, the difference exist in Dialects wich we use in the day life, but Classical Arabic is Classical Arabic wherever you are
