“And those who spend their wealth to be seen by people, and believe neither in Allah nor in the Last Day. Whoever takes Satan as a companion—what an evil companion he is! What harm would it have done them had they believed in Allah and the Last Day and spent from that which Allah had provided them? Allah knows them well.

(2) The connection in the passage is: “What harm would it have done them had they believed in Allah and the Last Day and spent?” For Allah does not wrong anyone—that is, He does not deprive or diminish anyone of the reward for his deeds by as much as an atom’s weight, the weight of an atom,
