Well if it was
دعني اØبك. هاذا ما استطيع Ùعله
I would've written it the way you suggested nadjet.

Hello Hamza
You wrote "...because this is..."
in English, I believe "because" and "for" are interchangeable. and that's what I did.
Personally, I don't like the word "because" and I try to use "for" where ever I can.
