Don't insult others

On the Day of Judgment, a person’s book of deeds will be given into his hands [and he will not see therein any of the good deeds he did, for Allah’s sake]. He will ask the Allah: “Why are my good deeds not recorded in here?” and Allah Ta’ala will answer:“They have been given to the ones you hurt and insulted by talking against them.” (At-Targhib wat Tarhib, Hadith: 4188)

Plz forgive me if I have hurt any brother / sister (knowingly or unknowingly)
