Narrated ‘Abdullah bin ‘Umar: The Prophet took hold of my shoulders and said, “Be in the world as if you were a stranger or a wayfarer.” Ibn ‘Umar used to say: “When you survive till the evening, do not expect to be alive till the morning; and when you survive till the morning do not except to be alive till the evening; (Do good deeds) when your are in good health before you fall sick, and (do good deeds) as long as you are alive before death strikes.” (Al-Bukhari)
This hadith illustrates the importance of treasuring time. If we are constantly thinking about our mortality, and how easily it can flee we will devote our time for more precious matters. Instead of watching two hours of tv tonight, try to read the Quran for just half an hour. Maybe before going to sleep pray a couple extra Nafl. During our day to day affairs lets try and keep Allah in our hearts, making dikhr of him so that we may draw closer to Him with every passing second. These are just small actions, we do not have to make it overly difficult on ourselves. Just a simple reminder that we will one day face Allah swt is enough to jolt our hearts.
