`Abdullah bin `Umar said, "Allah's Messenger (ﷺ) took hold of my shoulder and said, 'Be in this world as if you were a stranger or a traveler." The sub-narrator added: Ibn `Umar used to say, "If you survive till the evening, do not expect to be alive in the morning, and if you survive till the morning, do not expect to be alive in the evening, and take from your health for your sickness, and (take) from your life for your death."
Sahih al-Bukhari Book 81, Hadith 5
← Previous Hadith I heard the Prophet (ﷺ) saying, "A (small) place equal to an area occupied by a whip in Paradise is better than the (whole) world and whatever is in it; and an undertaking (journey) in the forenoon or in the afternoon for Allah's Cause, is better than the whole world and whatever is in it."

Sahih al-Bukhari Book 81, Hadith 4 Next Hadith → The Prophet (ﷺ) drew a square and then drew a line in the middle of it and let it extend outside the square and then drew several small lines attached to that central line, and said, "This is the human being, and this, (the square) in his lease of life, encircles him from all sides (or has encircled him), and this (line), which is outside (the square), is his hope, and these small lines are the calamities and troubles (which may befall him), and if one misses him, an-other will snap (i.e. overtake) him, and if the other misses him, a third will snap (i.e. overtake) him."
