@minhajulmredol I can feel the pain of losing a friend. My deepest condolences for the loss of your friend. Actually, all these tragedy shake our hearts. Such boat sinks often happen here too. I was a witness once, playing in the field by the riverbank, suddenly my eyes fell, two boats collided, both were sinking. I could hear womans screaming from the riverbank. Seeing this, everyone was going to help with small boats from the river bank. Nine people died that day. But you know what, being able to swim is a real blessing.
True but sometimes it doesn't help either. My friend knew how to swim, only Allah knows what exactly happened with him that he couldn't make it.
