So there is this app which is called microsoft maren that allows you to type arabic using an english keyboard (you type in english characters and it transliterate it to arabic). Thing is this app is only avaialable for windows , so I tried installing it with wine but the problem is I can't seem to find the option for microsoft maren in the languages which in windows would be with the arabic language... Any ideas ?

There's a good alternative quite similar to Maren made by google (and it supports many languages also).
You'll find a link to install it to google chrome. It wouldn't work across whole Ubuntu like Maren in Windows but I guess it's a partial solution.
