'Abdu'r-Rahman ibn Ziyad ibn An'am al-Ifriqi said, "My father told me that they were taking part in a sea raid in the time of Mu'awiya. He said, 'Our ship was right up against the ship of Abu Ayyub al-Ansari. When it was time for our midday meal, we invited him and he came over. He said, "You invited me, but even though I am fasting, I cannot avoid accepting your invitation because I heard the Messenger of Allah, may Allah bless him and grant him peace, say, 'A Muslim owes six things to his brother. If he neglects any of them, he has neglected an obligatory duty owed to his brother. He should return his greeting when he greets him. He should accept when he gives him an invitation. He should ask for mercy on him when he sneezes. He should give him good counsel when he asks him for advice.'"'"  

حَدَّثَنِي أَبِي أَنَّهُمْ كَانُوا غُزَاةً فِي الْبَحْرِ زَمَنَ مُعَاوِيَةَ فَانْضَمَّ مَرْكَبُنَا إِلَى مَرْكَبِ أَبِي أَيُّوبَ الأَنْصَارِيِّ فَلَمَّا حَضَرَ غَدَاؤُنَا أَرْسَلْنَا إِلَيْهِ فَأَتَانَا فَقَالَ دَعَوْتُمُونِي وَأَنَا صَائِمٌ فَلَمْ يَكُنْ لِي بُدٌّ مِنْ أَنْ أُجِيبَكُمْ لأَنِّي سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ إِنَّ لِلْمُسْلِمِ عَلَى أَخِيهِ سِتَّ خِصَالٍ وَاجِبَةٍ إِنْ تَرَكَ مِنْهَا شَيْئًا فَقَدْ تَرَكَ حَقًّا وَاجِبًا لأَخِيهِ عَلَيْهِ يُسَلِّمُ عَلَيْهِ إِذَا لَقِيَهُ وَيُجِيبُهُ إِذَا دَعَاهُ وَيُشَمِّتُهُ إِذَا عَطَسَ وَيَعُودُهُ إِذَا مَرِضَ وَيَحْضُرُهُ إِذَا مَاتَ وَيَنْصَحُهُ إِذَا اسْتَنْصَحَهُ قَالَ وَكَانَ مَعَنَا رَجُلٌ مَزَّاحٌ يَقُولُ لِرَجُلٍ أَصَابَ طَعَامَنَا جَزَاكَ اللَّهُ خَيْرًا وَبِرًّا فَغَضِبَ عَلَيْهِ حِينَ أَكْثَرَ عَلَيْهِ فَقَالَ لِأَبِي أَيُّوبَ مَا تَرَى فِي رَجُلٍ إِذَا قُلْتُ لَهُ جَزَاكَ اللَّهُ خَيْرًا وَبِرًّا غَضِبَ وَشَتَمَنِي ؟ فَقَالَ أَبُو أَيُّوبَ إِنَّا كُنَّا نَقُولُ إِنَّ مَنْ لَمْ يُصْلِحْهُ الْخَيْرُ أَصْلَحْهُ الشَّرُّ فَاقْلِبْ عَلَيْهِ فَقَالَ لَهُ حِينَ أَتَاهُ جَزَاكَ اللَّهُ شَرًّا وَعَرًّا فَضَحِكَ وَرَضِيَ وَقَالَ مَا تَدَعُ مُزَاحَكَ فَقَالَ الرَّجُلُ جَزَى اللَّهُ أَبَا أَيُّوبَ الْأَنْصَارِيَّ خَيْرًا  

to visit him when he is ill, to be with him when he dies, to accept when he invites him, and to ask for mercy on him when he sneezes."  

عَنِ النَّبِيِّ ﷺ قَالَ أَرْبَعٌ لِلْمُسْلِمِ عَلَى الْمُسْلِمِ يَعُودُهُ إِذَا مَرِضَ وَيَشْهَدُهُ إِذَا مَاتَ وَيُجِيبُهُ إِذَا دَعَاهُ وَيُشَمِّتُهُ إِذَا عَطَسَ  

Al-Bara' ibn 'Azib said, "The Messenger of Allah, may Allah bless him and grant him peace, instructed us to do seven things and forbade us seven. He instructed us to visit the sick, to join funeral processions, to bless people who sneeze, to fulfil our oaths, to help the wronged, to return the greeting, and to accept invitations. He forbade us gold rings, silver vessels, red (silk) saddle clothes, Qassi (silk and flax) garments, thick brocade, embroidered silk, and pure silk."  

عَنِ الْبَرَاءِ بْنِ عَازِبٍ قَالَ أَمَرَنَا رَسُولُ اللهِ ﷺ بِسَبْعٍ وَنَهَانَا عَنْ سَبْعٍ أَمَرَنَا بِعِيَادَةِ الْمَرِيضِ وَاتِّبَاعِ الْجَنَائِزِ وَتَشْمِيتِ الْعَاطِسِ وَإِبْرَارِ الْمُقْسِمِ وَنَصْرِ الْمَظْلُومِ وَإِفْشَاءِ السَّلاَمِ وَإِجَابَةِ الدَّاعِي وَنَهَانَا عَنْ خَوَاتِيمِ الذَّهَبِ وَعَنْ آنِيَةِ الْفِضَّةِ وَعَنِ الْمَيَاثِرِ وَالْقَسِّيَّةِ وَالإِسْتَبْرَقِ وَالدِّيبَاجِ وَالْحَرِيرِ  

Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "A Muslim owes another Muslim six duties." He was asked, "And what are they, Messenger of Allah?" He said, "To greet him when he meets him, to accept when he gives him an invitation, to give him good counsel when he asks for advice, to wish mercy on him when he sneezes and says, 'Praise be to Allah,' to visit him when he is ill, and to join the funeral procession when he dies."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ حَقُّ الْمُسْلِمِ عَلَى الْمُسْلِمِ سِتٌّ قِيلَ مَا هِيَ يَا رَسُولَ اللهِ؟ قَالَ إِذَا لَقِيتَهُ فَسَلِّمْ عَلَيْهِ وَإِذَا دَعَاكَ فَأَجِبْهُ وَإِذَا اسْتَنْصَحَكَ فَانْصَحْ لَهُ وَإِذَا عَطَسَ فَحَمِدَ اللَّهَ فَشَمِّتْهُ وَإِذَا مَرِضَ تَعُودُهُ وَإِذَا مَاتَ فَاتَّبِعْهُ
