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) is his lease of life (his or her day of death) 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, another will snap (i.e., overtake) him, and if the other misses him, a third will snap (i.e., overtake) him." [8:426-0.B]
