Al-Adab Al-Mufrad, Book 26, Hadith 464 (English) ⓘ

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."

حَدَّثَنَا عَبْدُ اللهِ بْنُ مُحَمَّدٍ، قَالَ‏:‏ حَدَّثَنَا ابْنُ عُيَيْنَةَ، عَنْ عَمْرٍو، عَنِ ابْنِ أَبِي مُلَيْكَةَ، عَنْ يَعْلَى بْنِ مَمْلَكٍ، عَنْ أُمِّ الدَّرْدَاءِ، عَنْ أَبِي الدَّرْدَاءِ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ‏:‏ مَنْ أُعْطِيَ حَظَّهُ مِنَ الرِّفْقِ فَقَدْ أُعْطِيَ حَظَّهُ مِنَ الْخَيْرِ، وَمَنْ حُرِمَ حَظَّهُ مِنَ الرِّفْقِ، فَقَدْ حُرِمَ حَظَّهُ مِنَ الْخَيْرِ، أَثْقَلُ شَيْءٍ فِي مِيزَانِ الْمُؤْمِنِ يَوْمَ الْقِيَامَةِ حُسْنُ الْخُلُقِ، وَإِنَّ اللَّهَ لَيُبْغِضُ الْفَاحِشَ الْبَذِيَّ‏.‏
