At one point or another, we have made delaying things an excuse. It's not a new phenomenon. Procrastinating of students is a form of delaying what's essential. However, one thing that we should never ever delay is practicing our deen.
If we only engrave in our hearts that death can come anytime without prior notice, we would not delay things. We only have one life to prove that we are worthy of Jannatul Firdaus, let's make the most of it. Let's work hard in this testing stage and gather our rewards in the afterlife.
