Teachers in the Ummah taught that:--
"He who seeks worldly wealth cannot dispense with commerce and profit;
he who seeks that of future life cannot dispense with Obedience and Service;
he who seeks the Master cannot avoid tests and suffering."
"Supplication takes away shame, pride drives out religion. A greedy man has
the nature of the devil. Where greed enters, there follows identification, where
identification is produced, an obstacle is created; where an obstacle is interposed,
work is interrupted; where interruption occurs, there follows infidelity and hell-fire".
