This is a true story from Middle East.
There was a car accident with some youths in them. Two officers were around who saw it and ran to help them out. One youth was dieing and one of the Police officer kept telling the youth to say "la illaha illalah" but the youth was only repeating the song he was listening to over and over again till death took him.
What you desire the most in this duniya, that will be on your tongue/mind at time of your death. Prophet (saws) said one who says the sahahda (before death) will go straight to paradise. But here the officer was telling him and reminding him to say the sahhada but couldn't.
Think about this, how do you want to go from this duniya. Praising Allah or singing the latest tune you heard?
