The fact that he committed suicide for such reasons as fear of Deportation back to a 3rd world country seems really extreme, I think there had to have been more too the story or perhaps to the man himself. Maybe he was mentally ill, only Allah knows. But I have to agree with the concerns the brother made about the son. This child now has to face many challenges alone; Now whether the child is muslim or not, living in the west is not easy. As to the comment made
he is a coward and will insha Allah be a loser in the hereafter
Brother, I'm sure you as well as anyone here know how HORRIBLE Jahannam is, so then you should know that to wish someone, espcially one you do know know, there is not a good practice. But my ears are closer to my mouth so i remind myself first.
Asalaamu Alaikum all
