Qur'an, Al-Fajr, Surah 89:15-20
When God tests you by giving you worldly honor and prosperity, you are inclined to say, "The Lord is kind." But when he tests you by withdrawing his favors, you say, "The Lord is cruel."
Yes! But you show no kindness to orphans; you do not compete with one another in feeding the poor. You grab with greedy hands the property of the weak; you are in love with material wealth.
