In Book 3 of Jalaluddin Rumi's Masnavi, a companion of the Prophet complains about repeatedly being defrauded in business transactions. In response, he is advised to stipulate a three-day trial or choice period (khiyar) in any sale where he fears deception. Rumi uses this practical commercial advice to deliver a broader spiritual teaching, contrasting the nature of patience and haste. He asserts that careful deliberation and patience are divine qualities originating from the Merciful, whereas impulsive haste is a characteristic of the accursed Satan.
