[Bukhari XXV. 464.] Abu'd-Darda' reported that the Prophet, may Allah bless him and grant him peace, said, "Whoever has been given his portion of compassion has been given his portion of good. Whoever is denied given his portion of compassion has been denied his portion of good. Good character will be the weightiest thing in the believer's balance on the Day of Rising . Allah hates a coarse, foul-mouthed person."
