“Indifference towards this world does not mean forbidding
what is permitted, or squandering wealth, rather indifference towards
this world means not thinking that what you have in your hand is more
reliable than what is in Allah’s Hand, and it means feeling that
the
reward for a calamity that befalls you is greater than that which
the
calamity makes you miss out on.’”
Sunan Ibn Majah Book 37, Hadith 1
