Anas ibn Malik reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "Do not hate one another nor envy one another nor shun one another. Slaves of Allah, be brothers! It is not lawful for a Muslim to refuse to speak to his brother (Muslim) for more than three nights."

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لاَ تَبَاغَضُوا وَلاَ تَحَاسَدُوا وَلاَ تَدَابَرُوا وَكُونُوا عِبَادَ اللهِ إِخْوَانًا وَلاَ يَحِلُّ لِمُسْلِمٍ أَنْ يَهْجُرَ أَخَاهُ فَوْقَ ثَلاَثِ لَيَالٍ

Abu Ayyub, the Companion of the Messenger of Allah, may Allah bless him and grant him peace, said, "It is not lawful for anyone to cut himself off from his Muslim brother for more than three nights so that when they meet, one of them turns his face away in avoidance and the other one turns his face away as well. The better of them is the one who initiates the greeting."

أَنَّ أَبَا أَيُّوبَ صَاحِبَ رَسُولِ اللهِ ﷺ أَخْبَرَهُ أَنَّ رَسُولَ اللهِ ﷺ قَالَ لاَ يَحِلُّ لأَحَدٍ أَنْ يَهْجُرَ أَخَاهُ فَوْقَ ثَلاَثِ لَيَالٍ يَلْتَقِيَانِ فَيَصُدُّ هَذَا وَيَصُدُّ هَذَا وَخَيْرُهُمَا الَّذِي يَبْدَأُ بِالسَّلامِ

Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "Do not hate one another nor contend with one another. Slaves of Allah, be brothers."

عَنِ النَّبِيِّ ﷺ قَالَ لاَ تَبَاغَضُوا وَلاَ تَنَافَسُوا وَكُونُوا عِبَادَ اللهِ إِخْوَانًا

Anas reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "Two people do not love each other in Allah Almighty or in Islam if the first wrong action that one of them does creates a split between them."

أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَا تَوَادَّ اثْنَانِ فِي اللهِ جَلَّ وَعَزَّ أَوْ فِي الإِسْلاَمِ فَيُفَرِّقُ بَيْنَهُمَا إِلاَّ بِذَنْبٍ يُحْدِثُهُ أَحَدُهُمَا

Hisham ibn 'Amir al-Ansari, the cousin of Anas ibn Malik whose father was killed in the Battle of Uhud, that he heard the Messenger of Allah, may Allah bless him and grant him peace, say, "It is not lawful for a Muslim to snub another Muslim for more than three nights. As long as they are cut off from each other, they are turning away from the Truth. The first of them to return to a proper state has his expiation for that inasmuch as he was the first to return to a proper state. If they die while they are cut off from each other, neither of them will ever enter the Garden. If one of them greets the other and he refuses to return the greeting or accept his greeting, then an angel returns the greeting to him and Shaytan answers the other."

أَنَّهُ سَمِعَ رَسُولَ اللهِ ﷺ قَالَ لاَ يَحِلُّ لِمُسْلِمٍ أَنْ يُصَارِمَ مُسْلِمًا فَوْقَ ثَلاَثٍ فَإِنَّهُمَا نَاكِبَانِ عَنِ الْحَقِّ مَا دَامَا عَلَى صِرَامِهِمَا وَإِنَّ أَوَّلَهُمَا فَيْئًا يَكُونُ كَفَّارَةً عَنْهُ سَبْقُهُ بِالْفَيْءِ وَإِنْ مَاتَا عَلَى صِرَامِهِمَا لَمْ يَدْخُلاَ الْجَنَّةَ جَمِيعًا أَبَدًا وَإِنْ سَلَّمَ عَلَيْهِ فَأَبَى أَنْ يَقْبَلَ تَسْلِيمَهُ وَسَلاَمَهُ رَدَّ عَلَيْهِ الْمَلَكُ وَرَدَّ عَلَى الْآخَرِ الشَّيْطَانُ

'A'isha mentioned that the Messenger of Allah, may Allah bless him and grant him peace, told her, "I can see you when you are angry or pleased." She asked, "How do you see that, Messenger of Allah?" He replied, "When you are pleased, you say, 'Yes, by the Lord of Muhammad.' But when you are angry, you say, 'No, by the Lord of Ibrahim.'" She said that she replied, "Yes, I only cut out your name."

قَالَ رَسُولُ اللهِ ﷺ إِنِّي لَأَعْرِفُ غَضَبَكِ وَرِضَاكِ قَالَتْ قُلْتُ وَكَيْفَ تَعْرِفُ ذَلِكَ يَا رَسُولَ اللهِ؟ قَالَ إِنَّكِ إِذَا كُنْتِ رَاضِيَةً قُلْتِ بَلَى وَرَبِّ مُحَمَّدٍ وَإِذَا كُنْتِ سَاخِطَةً قُلْتِ لاَ وَرَبِّ إِبْرَاهِيمَ قَالَتْ قُلْتُ أَجَلْ لَسْتُ أُهَاجِرُ إِلا اسْمَكَ
