"Whoever avoids lying while he is doing so falsely, a house will be built for him on the skirts of Paradise. Whoever avoids arguing while he is in the right, a house will be built for him in its midst. And whoever has good character, a house will be built for him in its heights."  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ تَرَكَ الْكَذِبَ وَهُوَ بَاطِلٌ بُنِيَ لَهُ فِي رَبَضِ الْجَنَّةِ وَمَنْ تَرَكَ الْمِرَاءَ وَهُوَ مُحِقٌّ بُنِيَ لَهُ فِي وَسَطِهَا وَمَنْ حَسَّنَ خُلُقَهُ بُنِيَ لَهُ فِي أَعْلاَهَا وَهَذَا الْحَدِيثُ حَدِيثٌ حَسَنٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ حَدِيثِ سَلَمَةَ بْنِ وَرْدَانَ عَنْ أَنَسِ بْنِ مَالِكٍ  

"It is enough sin for you that you never stop disputing."  

قَالَ رَسُولُ اللَّهِ ﷺ كَفَى بِكَ إِثْمًا أَنْ لاَ تَزَالَ مُخَاصِمًا وَهَذَا الْحَدِيثُ حَدِيثٌ غَرِيبٌ لاَ نَعْرِفُهُ إِلاَّ مِنْ هَذَا الْوَجْهِ  

"Do not argue with your brother, do not joke with him, and do not make a promise, only to not fulfill it."  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ تُمَارِ أَخَاكَ وَلاَ تُمَازِحْهُ وَلاَ تَعِدْهُ مَوْعِدَةً فَتُخْلِفَهُ
