Maulana Wahiduddin Khan | Soulveda
Just as there are two sides to every life in this world, there are two aspects of every act in relation to this world and the Hereafter. One aspect of each act is our acceptance of it, as what it is seen to be in this world. The other aspect is what results from this act, in terms of the Hereafter.
It is because life in this world is intended to be a testing-ground that the world of the Hereafter remains beyond our reach.
