"Nothing is heavier on the believer's Scale on the Day of Judgment than good character. For indeed Allah, Most High, is angered by the shameless obscene person."  

أَنَّ النَّبِيَّ ﷺ قَالَ مَا شَيْءٌ أَثْقَلُ فِي مِيزَانِ الْمُؤْمِنِ يَوْمَ الْقِيَامَةِ مِنْ خُلُقٍ حَسَنٍ وَإِنَّ اللَّهَ لَيَبْغَضُ الْفَاحِشَ الْبَذِيءَ  

"Nothing is placed on the Scale that is heavier than good character. Indeed the person with good character will have attained the rank of the person of fasting and prayer."  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ مَا مِنْ شَيْءٍ يُوضَعُ فِي الْمِيزَانِ أَثْقَلُ مِنْ حُسْنِ الْخُلُقِ وَإِنَّ صَاحِبَ حُسْنِ الْخُلُقِ لَيَبْلُغُ بِهِ دَرَجَةَ صَاحِبِ الصَّوْمِ وَالصَّلاَةِ  

The Messenger of Allah was asked about that for which people are admitted into Paradise the most and he said, "Conciousness of Allah, and good character." And he was asked about that for which people are admitted into the Fire the most, and he said, "The mouth and the private parts."  

سُئِلَ رَسُولُ اللَّهِ ﷺ عَنْ أَكْثَرِ مَا يُدْخِلُ النَّاسَ الْجَنَّةَ فَقَالَ «تَقْوَى اللَّهِ وَحُسْنُ الْخُلُقِ۔» وَسُئِلَ عَنْ أَكْثَرِ مَا يُدْخِلُ النَّاسَ النَّارَ فَقَالَ: «الْفَمُ وَالْفَرْجُ۔»  

'Abdullah bin Al-Mubarak explained good character, and then he said: "It is a smiling face, doing one's best in good, and refraining from harm."  

هُوَ بَسْطُ الْوَجْهِ وَبَذْلُ الْمَعْرُوفِ وَكَفُّ الأَذَى
