Hadith 5081
وَعَنْ أَبِي الدَّرْدَاءَ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «إِنَّ أَثْقَلَ شَيْءٍ يُوضَعُ فِي ميزانِ الْمُؤمن يومَ الْقِيَامَة خُلُقٌ حسنٌ وَإِنَّ اللَّهَ يُبْغِضُ الْفَاحِشَ الْبَذِيءَ» . رَوَاهُ التِّرْمِذِيُّ وَقَالَ: حَدِيث حسن صَحِيح. وروى أَبُو دَاوُد الفصلَ الأول
Abu Darda (may Allah be pleased with him) narrates from the Prophet (peace and blessings of Allah be upon him), he (peace and blessings of Allah be upon him) said: "On the Day of Resurrection, nothing will be placed in the believer’s scale heavier than good character, and Allah certainly does not like the one who is foul-mouthed and engages in obscene talk." (Tirmidhi), and he said: This hadith is Hasan Sahih, and Abu Dawood has narrated the first part. Its chain is authentic, narrated by Tirmidhi and Abu Dawood.
