“Live in this world as a traveller or a stranger”

“Live in this world as (if you are) a wayfarer or a stranger.” And Abdullah ibn Umar (May Allah be pleased with them both) used to say: “If you live till night, then do not wait for the next day (i.e. do not have hopes that you will live to the next day), and if you wake up in the morning do not have hope that you will live till the night. And take (advantage) from your health before your sickness and take advantage of your life before your death (i.e. do every possible obedience in your life before death comes to you for then no deeds can be performed.)”
