But Qur'an 5:9 instead says: "Let not a people’s enmity incite you to act otherwise than with justice. Be always just, that is nearer to righteousness."
A Muslim must never abandon justice.
Prophet Muhammad (sa) said, "He is not a believer whose stomach is filled while his neighbor goes hungry.”
Failing humanity means failing our faith. We serve to please God & b/c it's right—not for a reward.
