We are granted only one lifetime to prepare ourselves for the next life in the Hereafter. Death is the most certain endpoint from which there is no return to the previous world to make amendments for our actions. As per the Hadith, during the pre-death period we must lay the groundwork to qualify for Paradise in the Hereafter. Pre-death period is the testing ground and the post-death period is the hour of outcome.
Maulana Wahiduddin Khan
