The Messenger of Allah ﷺ said: By his good character a believer will attain the degree of one who prays during the night and fasts during the day.  

سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ إِنَّ الْمُؤْمِنَ لَيُدْرِكُ بِحُسْنِ خُلُقِهِ دَرَجَةَ الصَّائِمِ الْقَائِمِ  

The Prophet ﷺ said: There is nothing heavier than good character put in the scale of a believer on the Day of Resurrection. Abu al-Walid said: I heard 'Ata al-Kaikharani say: Abu Dawud said: His name is 'Ata b. Ya'qub. He is the maternal uncle of Ibrahim b. Nafi'. He is called Kaikharani or Kukharani.  

عَنِ النَّبِيِّ ﷺ قَالَ مَا مِنْ شَىْءٍ أَثْقَلُ فِي الْمِيزَانِ مِنْ حُسْنِ الْخُلُقِ قَالَ أَبُو الْوَلِيدِ قَالَ سَمِعْتُ عَطَاءً الْكَيْخَارَانِيَّ  

The Prophet ﷺ said: I guarantee a house in the surroundings of Paradise for a man who avoids quarrelling even if he were in the right, a house in the middle of Paradise for a man who avoids lying even if he were joking, and a house in the upper part of Paradise for a man who made his character good.  

قَالَ رَسُولُ اللَّهِ ﷺ أَنَا زَعِيمٌ بِبَيْتٍ فِي رَبَضِ الْجَنَّةِ لِمَنْ تَرَكَ الْمِرَاءَ وَإِنْ كَانَ مُحِقًّا وَبِبَيْتٍ فِي وَسَطِ الْجَنَّةِ لِمَنْ تَرَكَ الْكَذِبَ وَإِنْ كَانَ مَازِحًا وَبِبَيْتٍ فِي أَعْلَى الْجَنَّةِ لِمَنْ حَسَّنَ خُلُقَهُ  

neither the Jawwaz nor the Jazari will enter paradise. He said that the Jawwaz is the one who is coarse and uncivil.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَدْخُلُ الْجَنَّةَ الْجَوَّاظُ وَلاَ الْجَعْظَرِيُّ قَالَ وَالْجَوَّاظُ الْغَلِيظُ الْفَظُّ
