Salam Claudia, In Arabic, the singular word (سماء) refers to the actual sky, as in (the sky is blue = السمـاء زرقـاء). However, the plural form (*سـمـاوات) usually refers to "the heavens", and thus (سافـر إلـى السماوات) has the same meaning as (passing away), in English. P.s: There is actually an Iraqi city called (الـسـمـاوة). I don't know the exact context of your source, but there is a chance he might be going to (الـسـمـاوة) instead of going to the heavens, especially if he is planning to come back. Sometimes a small spelling mistake can make the difference between going to Samawah and going to the heavens :)

Correct sentence : سافر إلى السماوات ولا أظنه سيعود But we say in Arabic: صَعَدَتْ رُوْحُهُ إلى بَارِئِها ( خالِقِها It means: مات And we can say: صَعَدَتْ روحه إلى السماء ولن يعود Exactly the same meaning as in Italian I hope that is good for you Enjoy your time with the Arabic language :))

I'm not the greatest in arabic, but what you typed literally means " He travelled to the skies and i don't think he will be coming back ". I Believe anything around " travelling to the skies " would mean he has passed away in any language, but judging by what's said at the end of the sentence " not coming back " i really doubt that sentence was talking about a death, hope this helped!
