As a muslim I believe in the test of the grave along with my belief in Allah the creator, Lord of all the worlds, the prophets, like Abraham, Noah, Joseph, Jonas, Moses, Jesus, and Muhammed (peace be upon them all).
That test will be the asking of three questions will be: who is your Lord? who is your prophet? and what is your deen(way of life)?
The answers that I will see me right, are My Lord is Allah, my Prophet is Muhammed, and my deen is Islam.
To be able to answer like this, it is down to me in this life to seek knowledge on all three, seek as much knowledge as I am able on my Lord, on my prophet, and my teen, and apply that knowledge. I pray Allah makes this task easy for me, and for you.
