“O Past that has departed and is gone, I will not cry over you. You will not see me remembering you, not even for a moment, because you have traveled away from me never to return.
O Future, you are in the realm of the unseen, so I will not be obsessed by your dreams. I will not be preoccupied about what is to come because tomorrow is nothing and has not yet been created.”
-Aaidh ibn Abdullah al-Qarni
