Volume 8, Book 76, Number 426:
Narrated ‘Abdullah:
The Prophet 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.”
