It is narrated from Hazrat Abu Musa (may Allah be pleased with him) that he said: A good companion is better than solitude, and solitude is better than a bad companion. Beware! The example of a good companion is like that of perfume; even if he does not give you any, still by being near him you will become fragrant. And beware! The example of a bad companion is like that of a furnace’s smoke; even if it does not burn you, its smell will reach you. Beware! The heart is called“qalb”because of its tendency to turn. Beware! The example of the heart is like a feather hanging from a tree in the open air; the wind keeps turning it over and over, up and down.
