Verily I saw water become putrid in its stagnation, and become sweet when it flows. And the lions would not be fierce if they didn’t leave their grounds, and the arrow would not strike if it didn’t leave the bow.

In leaving your destiny will change, and in emigration you will become precious, like gold. And God knows.
IMAM AL-SHAFI’I, 767–820 AD
