"May Allah reward you", seems to work fine.
First of all, the correct statement is Jazaak Allahu Khairan. If you do not ad the Khairan, then what you are saying is either may Allah reward you, or may Allah punish you. Khairan means "good", so you are asking that Allah rewards a person with good. But the word Jazaa' alone can be for reward or punishment, as it simply means "recompense". The proper response to Jazaak Allahu Khairan (May Allah reward you with good)is: Wa Iyyaak ( and to you).
say: Allah yerda aleek , if you are talking to a male. say: Allah yerda aleeki , if you are talking to a female. say: Allah yerda aleekom, if you are talking to a group of people.
In Islam, you can say "Mabrook" to offer congratulations.
Allah yahmik or hamak'Allah حماك الله :)
Taqabal Allah a'malakum May Allah accept your ibadah or Taqabal Allah al ziyarah May Allah accept your ziyarah you dont have to mention Umrah they will know what your talking about ;)
Islam (Muslims) is a religion, not a language. but if you mean Arabic it is "Shukaran" The answer, above, is correct. Now, the real way you should thank any Muslim, is not to say "thank you", but you're supposed to say "May God reward you with good" In Arabic: Jazaak Allahu Khairan.
Yes, it is appropriate, and Muslims often show sympathy and support in such occasions by saying many things, including: "Eternity is for Allah alone" "May Allah grant you with patience" "May Allah reward/recompend you for your patience"
May Allah be with you : alla ykon ma'ak written : الله يكون معك
Hadhrat Abu Bakr RA. May Allah reward him highly for the unlimited scarifices he made for Islam.
ALLAH is the one and only god. ALLAH is living, never dies.
Allah yisalmic (female) or Allah yisalmac (male) meaning May God give you peace.
You can show your gratitude by saying "jazakillah khair" back to me, which means "may Allah reward you with goodness."
