Messenger of Allah ﷺ said, "Do not hate one another, and do not be jealous of one another, and do not desert each other, and O, Allah's worshipers! Be brothers. Lo! It is not permissible for any Muslim to desert (not talk to) his brother (Muslim) for more than three days."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ تَبَاغَضُوا وَلاَ تَحَاسَدُوا وَلاَ تَدَابَرُوا وَكُونُوا عِبَادَ اللَّهِ إِخْوَانًا وَلاَ يَحِلُّ لِمُسْلِمٍ أَنْ يَهْجُرَ أَخَاهُ فَوْقَ ثَلاَثَةِ أَيَّامٍ  

Messenger of Allah ﷺ said, "Do not hate one another, nor be jealous of one another; and do not desert one another, but O Allah's worshipers! Be Brothers! And it is unlawful for a Muslim to desert his brother Muslim (and not to talk to him) for more than three nights."  

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

Messenger of Allah ﷺ said, "It is not lawful for a man to desert his brother Muslim for more than three nights. (It is unlawful for them that) when they meet, one of them turns his face away from the other, and the other turns his face from the former, and the better of the two will be the one who greets the other first."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ يَحِلُّ لِرَجُلٍ أَنْ يَهْجُرَ أَخَاهُ فَوْقَ ثَلاَثِ لَيَالٍ يَلْتَقِيَانِ فَيُعْرِضُ هَذَا وَيُعْرِضُ هَذَا وَخَيْرُهُمَا الَّذِي يَبْدَأُ بِالسَّلاَمِ  

The Prophet ﷺ said, "It is not lawful for a Muslim to desert (not to speak to) his brother Muslim for more than three days while meeting, one turns his face to one side and the other turns his face to the other side. Lo! The better of the two is the one who starts greeting the other."  

عَنِ النَّبِيِّ ﷺ قَالَ لاَ يَحِلُّ لِمُسْلِمٍ أَنْ يَهْجُرَ أَخَاهُ فَوْقَ ثَلاَثٍ يَلْتَقِيَانِ فَيَصُدُّ هَذَا وَيَصُدُّ هَذَا وَخَيْرُهُمَا الَّذِي يَبْدَأُ بِالسَّلاَمِ وَذَكَرَ سُفْيَانُ أَنَّهُ سَمِعَهُ مِنْهُ ثَلاَثَ مَرَّاتٍ  

The deeds are presented on every Thursday and Monday and Allah, the Exalted and Glorious. grants pardon to every person who does not associate anything with Allah except the person in whose (heart) there is rancour against his brother. It would be said: Put both of them off until they are reconciled.  

تُعْرَضُ الأَعْمَالُ فِي كُلِّ يَوْمِ خَمِيسٍ وَاثْنَيْنِ فَيَغْفِرُ اللَّهُ ﷻ فِي ذَلِكَ الْيَوْمِ لِكُلِّ امْرِئٍ لاَ يُشْرِكُ بِاللَّهِ شَيْئًا إِلاَّ امْرَأً كَانَتْ بَيْنَهُ وَبَيْنَ أَخِيهِ شَحْنَاءُ فَيُقَالُ ارْكُوا هَذَيْنِ حَتَّى يَصْطَلِحَا ارْكُوا هَذَيْنِ حَتَّى يَصْطَلِحَا  

I heard Allah's Apostle ﷺ as saying: Verily, the Satan has lost all hopes that the worshippers would ever worship (him) in the peninsula of Arabia, but he (is hopeful) that he would sow the seed of dissension amongst them.  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ إِنَّ الشَّيْطَانَ قَدْ أَيِسَ أَنْ يَعْبُدَهُ الْمُصَلُّونَ فِي جَزِيرَةِ الْعَرَبِ وَلَكِنْ فِي التَّحْرِيشِ بَيْنَهُمْ  

The Prophet ﷺ said: It is not allowable for a Muslim to keep apart from his brother for more than three days, for one who does so and dies will enter Hell.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ يَحِلُّ لِمُسْلِمٍ أَنْ يَهْجُرَ أَخَاهُ فَوْقَ ثَلاَثٍ فَمَنْ هَجَرَ فَوْقَ ثَلاَثٍ فَمَاتَ دَخَلَ النَّارَ  

AbuKhirash heard the Messenger of Allah ﷺ say: If one keeps apart from his brother for a year, it is like shedding his blood.  

أَنَّهُ سَمِعَ رَسُولَ اللَّهِ ﷺ يَقُولُ مَنْ هَجَرَ أَخَاهُ سَنَةً فَهُوَ كَسَفْكِ دَمِهِ  

The Prophet ﷺ said: It is not allowable for a believer to keep from a believer for more than three days. If three days pass, he should meet him and give him a salutation, and if he replies to it they will both have shared in the reward; but if he does not reply he will bear his sin (according to Ahmad's version) and the one who gives the salutation will have come forth from the sin of keeping apart.  

أَنَّ النَّبِيَّ ﷺ قَالَ لاَ يَحِلُّ لِمُؤْمِنٍ أَنْ يَهْجُرَ مُؤْمِنًا فَوْقَ ثَلاَثٍ فَإِنْ مَرَّتْ بِهِ ثَلاَثٌ فَلْيَلْقَهُ فَلْيُسَلِّمْ عَلَيْهِ فَإِنْ رَدَّ عَلَيْهِ السَّلاَمَ فَقَدِ اشْتَرَكَا فِي الأَجْرِ وَإِنْ لَمْ يَرُدَّ عَلَيْهِ فَقَدْ بَاءَ بِالإِثْمِ زَادَ أَحْمَدُ وَخَرَجَ الْمُسَلِّمُ مِنَ الْهِجْرَةِ
