It is recommended to pass water and milk etc., to the right of the one who drinks first

Anas b. Malik reported that there was brought to Allah's Messenger (ﷺ) a cup of milk mixed with water, while there was on his right a desert Arab and on his left Abu Bakr. He (the Prophet) drank; he then gave it to the desert Arab and said:

(Give to one) who is on the right, then again who is on the right.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنِ ابْنِ شِهَابٍ، عَنْ أَنَسِ بْنِ مَالِكٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أُتِيَ بِلَبَنٍ قَدْ شِيبَ بِمَاءٍ وَعَنْ يَمِينِهِ أَعْرَابِيٌّ وَعَنْ يَسَارِهِ أَبُو بَكْرٍ فَشَرِبَ ثُمَّ أَعْطَى الأَعْرَابِيَّ وَقَالَ ‏

‏ الأَيْمَنَ فَالأَيْمَنَ ‏

‏ ‏.‏

Anas reported:

The Messenger of Allah (ﷺ) came to Medina when I was ten years old and he died when I was twenty years old. My mother exhorted me to serve him. He (the Prophet) came to our house, and we ruined a flabby goat for him and mixed it (the milk) with water from the well of the house. Allah's Messenger (ﷺ) drank that. Umar and Abu Bakr on his left side said to him: Allah's Messenger (ﷺ) , give it to Abu Bakr, but he (the Prophet) gave it to the desert Arab who was on his right. Allah's Messenger (ﷺ) said: He who is on the right, then he who is on the right.

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَمْرٌو النَّاقِدُ، وَزُهَيْرُ بْنُ حَرْبٍ، وَمُحَمَّدُ بْنُ عَبْدِ، اللَّهِ بْنِ نُمَيْرٍ - وَاللَّفْظُ لِزُهَيْرٍ - قَالُوا حَدَّثَنَا سُفْيَانُ بْنُ عُيَيْنَةَ، عَنِ الزُّهْرِيِّ، عَنْ أَنَسٍ، قَالَ قَدِمَ النَّبِيُّ صلى الله عليه وسلم الْمَدِينَةَ وَأَنَا ابْنُ عَشْرٍ وَمَاتَ وَأَنَا ابْنُ عِشْرِينَ وَكُنَّ أُمَّهَاتِي يَحْثُثْنَنِي عَلَى خِدْمَتِهِ فَدَخَلَ عَلَيْنَا دَارَنَا فَحَلَبْنَا لَهُ مِنْ شَاةٍ دَاجِنٍ وَشِيبَ لَهُ مِنْ بِئْرٍ فِي الدَّارِ فَشَرِبَ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ لَهُ عُمَرُ وَأَبُو بَكْرٍ عَنْ شِمَالِهِ يَا رَسُولَ اللَّهِ أَعْطِ أَبَا بَكْرٍ ‏.‏ فَأَعْطَاهُ أَعْرَابِيًّا عَنْ يَمِينِهِ وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏

‏ الأَيْمَنَ فَالأَيْمَنَ ‏

‏ ‏.‏

Anas b. Malik reported:

Allah's Messenger (ﷺ) came to our house and he asked for a drink. We milked a goat for him and then mixed it (the milk) with the water of this well of mine. I gave it to Allah's Messenger (ﷺ) and he drank it, while Abu Bakr was on his left and 'Umar was in front of him, and a desert Arab was on his right. When Allah's Messenger (ﷺ) had finished the drink, Umar said: Allah's Messenger (ﷺ) , here is Abu Bakr, give him to drink; but Allah's Messenger (ﷺ) gave it to the desert Arab and he left out Abu Bakr and Umar. And Allah's Messenger (ﷺ) said: Those on the right, those on the right, those on the right (deserve preference). Anas said: This is the Sunnah, this is the Sunnah, this is the Sunnah.

حَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ، وَقُتَيْبَةُ، وَعَلِيُّ بْنُ حُجْرٍ، قَالُوا حَدَّثَنَا إِسْمَاعِيلُ، - وَهُوَ ابْنُ جَعْفَرٍ - عَنْ عَبْدِ اللَّهِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ مَعْمَرِ بْنِ حَزْمٍ أَبِي طُوَالَةَ الأَنْصَارِيِّ، أَنَّهُ سَمِعَ أَنَسَ بْنَ مَالِكٍ، ح وَحَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ بْنِ قَعْنَبٍ، - وَاللَّفْظُ لَهُ - حَدَّثَنَا سُلَيْمَانُ، - يَعْنِي ابْنَ بِلاَلٍ - عَنْ عَبْدِ اللَّهِ بْنِ عَبْدِ الرَّحْمَنِ، أَنَّهُ سَمِعَ أَنَسَ بْنَ مَالِكٍ، يُحَدِّثُ قَالَ أَتَانَا رَسُولُ اللَّهِ صلى الله عليه وسلم فِي دَارِنَا فَاسْتَسْقَى فَحَلَبْنَا لَهُ شَاةً ثُمَّ شُبْتُهُ مِنْ مَاءِ بِئْرِي هَذِهِ - قَالَ - فَأَعْطَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم فَشَرِبَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَأَبُو بَكْرٍ عَنْ يَسَارِهِ وَعُمَرُ وُجَاهَهُ وَأَعْرَابِيٌّ عَنْ يَمِينِهِ فَلَمَّا فَرَغَ رَسُولُ اللَّهِ صلى الله عليه وسلم مِنْ شُرْبِهِ قَالَ عُمَرُ هَذَا أَبُو بَكْرٍ يَا رَسُولَ اللَّهِ ‏.‏ يُرِيهِ إِيَّاهُ فَأَعْطَى رَسُولُ اللَّهِ صلى الله عليه وسلم الأَعْرَابِيَّ وَتَرَكَ أَبَا بَكْرٍ وَعُمَرَ وَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏

‏ الأَيْمَنُونَ الأَيْمَنُونَ الأَيْمَنُونَ ‏

‏ ‏.‏ قَالَ أَنَسٌ فَهِيَ سُنَّةٌ فَهِيَ سُنَّةٌ فَهِيَ سُنَّةٌ ‏.‏

Sahl b. Sa'd Sa'idi reported that Allah's Messenger (ﷺ) was given a drink, and he drank from that, and there was on his right side a boy. and on his left some old men. He said to the boy:

Do you permit me to give it to them (the old men), but that boy said: by God. I will not give preference at your hand over me in my share. He (the narrator) said that Allah's Messenger (ﷺ) then gave it in his hand.

حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، عَنْ مَالِكِ بْنِ أَنَسٍ، فِيمَا قُرِئَ عَلَيْهِ عَنْ أَبِي حَازِمٍ، عَنْ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم أُتِيَ بِشَرَابٍ فَشَرِبَ مِنْهُ وَعَنْ يَمِينِهِ غُلاَمٌ وَعَنْ يَسَارِهِ أَشْيَاخٌ فَقَالَ لِلْغُلاَمِ ‏"‏ أَتَأْذَنُ لِي أَنْ أُعْطِيَ هَؤُلاَءِ ‏"‏ ‏.‏ فَقَالَ الْغُلاَمُ لاَ ‏.‏ وَاللَّهِ لاَ أُوثِرُ بِنَصِيبِي مِنْكَ أَحَدًا ‏"‏ ‏.‏ قَالَ فَتَلَّهُ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي يَدِهِ ‏.‏

This hadith is reported on the authority of Sahl b. Sa'd with a slight variation of wording.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِي حَازِمٍ، ح وَحَدَّثَنَاهُ قُتَيْبَةُ بْنُ، سَعِيدٍ حَدَّثَنَا يَعْقُوبُ، - يَعْنِي ابْنَ عَبْدِ الرَّحْمَنِ الْقَارِيَّ - كِلاَهُمَا عَنْ أَبِي حَازِمٍ، عَنْ سَهْلِ، بْنِ سَعْدٍ عَنِ النَّبِيِّ صلى الله عليه وسلم ‏.‏ بِمِثْلِهِ وَلَمْ يَقُولاَ فَتَلَّهُ ‏.‏ وَلَكِنْ فِي رِوَايَةِ يَعْقُوبَ قَالَ فَأَعْطَاهُ إِيَّاهُ ‏.‏
