Question [Q] How to add Arabic input language to Gingerbread 2.3.6 Samsung Galaxy Y GT-B5512?

Hello everyone,
I have Samsung Galaxy Y Duos GT-B5512 Gingerbread 2.3.6 (which has touchscreen and physical keyboard) and I just flashed it with HatyonRom V1.1, I want to add English/Arabic Input Languages so I can swap easily with the "AB" button in the phone, the problem is there no Arabic input language in the phone, I can't add the Arabic Keyboard "such as GO! Keyboard" cause it doesn't support phyical keyboard.
So I just need to add Arabic input language to my phone.

Please I need help for my complicated problem.

Thanks in advance,
