[أبوعدنان مديح عبد الهادي]

Brother Mohammad - I agree with you -to a certain extent- that it's not befitting of a Muslim to speak that way but I wouldn't go as far as saying it’s riya'. On the other hand, I agree with brother Abdullah that it's a "way of life". I used to live –for few years- in the heart of Brooklyn and that’s pretty “normal”. They pick it up by mimicking friends, people they admire, and –sometimes even- parents. As you know At-tab3u sarraq.

Having said that I believe that with time this brother can change; I know many friends who used to talk like that but have changed. With knowledge and the proper company, he will pick up the “samt” befitting of a Muslim. But that takes time. I hope he has access to someone to teach him tawheed and sunnah. That would be the best thing to happen to him after embracing Islam.
That’s what matters the most now. There are many well spoken and eloquent converts (some are “dua’ts”!) but unfortunately they are sufis or of some deviant belief.
