Could you please tell me what this means and an appropriate response???

Sadaka laho aladim…

Thank you!

In Arabic: ??? ??? ???
It means: God Almighty has spoken the truth. We say it after quoting a verse from the Quran.
When said, one replies: Allaho Al-karim, God is indeed generous. People probably respond with something different in other Muslim countries, but that’s what we always said at school.

Thank you so much, this was very special.
