Reminder: Do not wrong anyone

Do not wrong anyone, for wrongdoing will become layers of darkness on the Day of Resurrection. How heavy those darknesses will weigh upon hearts on the day when secrets are laid bare and deeds are weighed. So beware lest a fleeting power, a passing anger, or a domineering desire lead you to lay your hand upon a right that is not yours, or cause you to harm a servant of God in a manner that neither God approves nor the conscience can accept.
Do not backbite people even if they backbite you, for backbiting is a hidden disease that consumes good deeds just as fire consumes dry wood. Do not insult them even if they insult you, for once a word leaves the mouth of its speaker it never returns to him, but remains as a witness against him on the Day of Reckoning. Do not look down upon them even if they look down upon you, for many who appear weak in the eyes of people are great in the sight of God, and many whom the eyes revere with awe are small and insignificant before Him.
Do not violate their honour even if they violate yours, and do not transgress against them even if they transgress against you; for the truly noble person is the one who masters himself in moments of anger and restrains his harm even when he has the power to harm. The true test is not that you repay injury with injury—for that is something anyone can do—but that you rise above the pettiness of lesser souls and choose to forgive when anger tempts you towards revenge.
Recognise the sanctity of people’s honour and their property, for in the sight of God they are of great consequence. God has made them a safeguard for human dignity and a protection for one’s sense of honour. Therefore do not trample upon this sanctity with the foot of greed, nor violate it with the hand of aggression, nor make your tongue a sword with which you wound the dignity of others.
And when you live among people, establish for yourself a principle from which you never depart: that you should meet God with a sound heart, a pure hand, and a guarded tongue. Walk through your life light of burden, not weighed down by the rights of others, not followed by the complaint of the oppressed, nor pursued by the tear of one who has been wronged.
For the happiest of people on the Day of Resurrection will be the one who comes before God with a pure heart, bearing no injustice against anyone, no claim raised against him by another, no right he has violated, and no dignity he has dishonoured. On that day he will proceed with a tranquil soul and a contented conscience, having escaped from the darkness of injustice into the light of justice, and from the narrowness of this world into the vast mercy of God.
