Are both rich and poor people in trial?

 

Verses 15-20 of Chapter 89:
As for man, whenever his Lord tries him and honors and blesses him, he says, "My Lord has honored me." But when He tests him and restricts his provisions for him, he says, "My Lord has disgraced me." Indeed not! But you do not treat the orphan with respect, and you do not urge one another to feed the poor, and you devour the whole inheritance greedily, and you love the wealth with all yow hearts.
