Found this on the internet, and feeling like to share this video.
For those who still not believe that He exists...
Read the Qur'an, follow the hadith. Before "that day" comes...
QS Al-Mulk 6-11
For those who disbelieve in their Lord, there is the torment of Hell, and it is an evil abode. When they are flung into it, they will hear its roaring, and it will be boiling up,
as though bursting with rage. Every time a crowd is cast into it, its keepers will ask them, "Did not a warner come to you?"
They will answer, "Yes, a warner did come to us, but we belied him and said, `Allah has not sent down anything: you are in grave error'!"
And they will add, "Had we only listened or understood, we would not now be among the dwellers of the blazing Fire.
" Thus will they confess their own sin. Damned be the dwellers of Hell!
