Could you please provide some context about where you heard this word? This could help me understand its meaning and potentially find an Arabic equivalent.
For example:

* What was the context? (was it in a conversation, a text, a song, etc.)
* What was the general topic being discussed?
With more information, I can better assist you in finding the meaning of "besslama" in Arabic.
