The best among your are the ones of the best character

Abdullah bin 'Amr mentioned Messenger of Allah ﷺ saying that he was neither a Fahish nor a Mutafahish. Abdullah bin 'Amr added, Messenger of Allah ﷺ said, 'The best among you are those who have the best manners and character.'  

دَخَلْنَا عَلَى عَبْدِ اللَّهِ بْنِ عَمْرٍو حِينَ قَدِمَ مَعَ مُعَاوِيَةَ إِلَى الْكُوفَةِ فَذَكَرَ رَسُولَ اللَّهِ ﷺ فَقَالَ لَمْ يَكُنْ فَاحِشًا وَلاَ مُتَفَحِّشًا وَقَالَ قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ مِنْ أَخْيَرِكُمْ أَحْسَنَكُمْ خُلُقًا  

ʿAisha said that the Jews came to the Prophet ﷺ and said, "As-Samu 'Alaikum" (death be on you). ʿAisha said (to them), "(Death) be on you, and may Allah curse you and shower His wrath upon you!" The Prophet ﷺ said, "Be calm, O ʿAisha ! You should be kind and lenient, and beware of harshness and Fuhsh (i.e. bad words)." She said (to the Prophet), "Haven't you heard what they (Jews) have said?" He said, "Haven't you heard what I have said (to them)? I said the same to them, and my invocation against them will be accepted while theirs against me will be rejected (by Allah). "  

أَنَّ يَهُودَ أَتَوُا النَّبِيَّ ﷺ فَقَالُوا السَّامُ عَلَيْكُمْ فَقَالَتْ عَائِشَةُ عَلَيْكُمْ وَلَعَنَكُمُ اللَّهُ وَغَضِبَ اللَّهُ عَلَيْكُمْ قَالَ مَهْلاً يَا عَائِشَةُ عَلَيْكِ بِالرِّفْقِ وَإِيَّاكِ وَالْعُنْفَ وَالْفُحْشَ قَالَتْ أَوَلَمْ تَسْمَعْ مَا قَالُوا قَالَ أَوَلَمْ تَسْمَعِي مَا قُلْتُ رَدَدْتُ عَلَيْهِمْ فَيُسْتَجَابُ لِي فِيهِمْ وَلاَ يُسْتَجَابُ لَهُمْ فِيَّ  

The Prophet ﷺ was not one who would abuse (others) or say obscene words, or curse (others), and if he wanted to admonish anyone of us, he used to say: "What is wrong with him, his forehead be dusted!"  

لَمْ يَكُنِ النَّبِيُّ ﷺ سَبَّابًا وَلاَ فَحَّاشًا وَلاَ لَعَّانًا كَانَ يَقُولُ لأَحَدِنَا عِنْدَ الْمَعْتَبَةِ مَا لَهُ تَرِبَ جَبِينُهُ  

A man asked permission to enter upon the Prophet. When the Prophet ﷺ saw him, he said, "What an evil brother of his tribe! And what an evil son of his tribe!" When that man sat down, the Prophet ﷺ behaved with him in a nice and polite manner and was completely at ease with him. When that person had left, 'Aisha said (to the Prophet). "O Allah's Apostle! When you saw that man, you said so-and-so about him, then you showed him a kind and polite behavior, and you enjoyed his company?" Messenger of Allah ﷺ said, "O 'Aisha! Have you ever seen me speaking a bad and dirty language? (Remember that) the worst people in Allah's sight on the Day of Resurrection will be those whom the people leave (undisturbed) to be away from their evil (deeds)."  

أَنَّ رَجُلاً اسْتَأْذَنَ عَلَى النَّبِيِّ ﷺ فَلَمَّا رَآهُ قَالَ بِئْسَ أَخُو الْعَشِيرَةِ وَبِئْسَ ابْنُ الْعَشِيرَةِ فَلَمَّا جَلَسَ تَطَلَّقَ النَّبِيُّ ﷺ فِي وَجْهِهِ وَانْبَسَطَ إِلَيْهِ فَلَمَّا انْطَلَقَ الرَّجُلُ قَالَتْ لَهُ عَائِشَةُ يَا رَسُولَ اللَّهِ حِينَ رَأَيْتَ الرَّجُلَ قُلْتَ لَهُ كَذَا وَكَذَا ثُمَّ تَطَلَّقْتَ فِي وَجْهِهِ وَانْبَسَطْتَ إِلَيْهِ فَقَالَ رَسُولُ اللَّهِ ﷺ يَا عَائِشَةُ مَتَى عَهِدْتِنِي فَحَّاشًا إِنَّ شَرَّ النَّاسِ عِنْدَ اللَّهِ مَنْزِلَةً يَوْمَ الْقِيَامَةِ مَنْ تَرَكَهُ النَّاسُ اتِّقَاءَ شَرِّهِ
