Sahih al-Bukhari 5163
Narrated Anas bin Malik:
"Whenever the Prophet (ﷺ) passed by (my mother Um-Sulaim) he used to enter
     her and greet her. Anas further said: Once the Prophet (ﷺ) way a 
     bridegroom during his marriage with Zainab, Um Sulaim said to me, "Let
     us give a gift to Allah's Messenger (ﷺ) ." I said to her, "Do it." So she 
     prepared Haisa (a sweet dish) made from dates, butter and dried 
     yoghurt and she sent it with me to him. I took it to him and he said, 
     "Put it down," and ordered me to call some men whom he named, and to 
     invite whomever I would meet. I did what he ordered me to do, and when
     I returned, I found the house crowded with people and saw the Prophet (ﷺ) 
     keeping his hand over the Haisa and saying over it whatever Allah 
     wished (him to say). Then he called the men in batches of ten to eat 
     of it, and he said to them, "Mention the Name of Allah, and each man 
     should eat of the dish the nearest to him." When all of them had 
     finished their meals, some of them left and a few remained there 
     talking, over which I felt unhappy. Then the Prophet (ﷺ) went out towards 
     the dwelling places (of his wives) and I too, went out after him and 
     told him that those people had left. Then he returned and entered his 
     dwelling place and let the curtains fall while I was in (his) dwelling
     place, and he was reciting the Verses:-- 'O you who believe! Enter not
     the Prophet's house until leave is given you for a meal, (and then) 
     not (as early as) to what for its preparation. But when you are 
     invited, enter, and when you have taken your meals, disperse without 
     sitting for a talk. Verily such (behavior) annoys the Prophet; and he 
     would be shy of (asking) you (to go), but Allah is not shy of (telling
     you) the Truth.' (33-53) Abu Uthman said: Anas said, "I served the 
     Prophet for ten years."
وَقَالَ إِبْرَاهِيمُ عَنْ أَبِي عُثْمَانَ ـ وَاسْمُهُ الْجَعْدُ ـ عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ مَرَّ بِنَا فِي مَسْجِدِ بَنِي رِفَاعَةَ فَسَمِعْتُهُ يَقُولُ كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا مَرَّ بِجَنَبَاتِ أُمِّ سُلَيْمٍ دَخَلَ عَلَيْهَا فَسَلَّمَ عَلَيْهَا، ثُمَّ قَالَ كَانَ النَّبِيُّ صلى الله عليه وسلم عَرُوسًا بِزَيْنَبَ فَقَالَتْ لِي أُمُّ سُلَيْمٍ لَوْ أَهْدَيْنَا لِرَسُولِ اللَّهِ صلى الله عليه وسلم هَدِيَّةً فَقُلْتُ لَهَا افْعَلِي‏.‏ فَعَمَدَتْ إِلَى تَمْرٍ وَسَمْنٍ وَأَقِطٍ، فَاتَّخَذَتْ حَيْسَةً فِي بُرْمَةٍ، فَأَرْسَلَتْ بِهَا مَعِي إِلَيْهِ، فَانْطَلَقْتُ بِهَا إِلَيْهِ فَقَالَ لِي ‏"‏ ضَعْهَا ‏"‏‏.‏ ثُمَّ أَمَرَنِي فَقَالَ ‏"‏ ادْعُ لِي رِجَالاً ـ سَمَّاهُمْ ـ وَادْعُ لِي مَنْ لَقِيتَ ‏"‏‏.‏ قَالَ فَفَعَلْتُ الَّذِي أَمَرَنِي فَرَجَعْتُ فَإِذَا الْبَيْتُ غَاصٌّ بِأَهْلِهِ، فَرَأَيْتُ النَّبِيَّ صلى الله عليه وسلم وَضَعَ يَدَيْهِ عَلَى تِلْكَ الْحَيْسَةِ، وَتَكَلَّمَ بِهَا مَا شَاءَ اللَّهُ، ثُمَّ جَعَلَ يَدْعُو عَشَرَةً عَشَرَةً، يَأْكُلُونَ مِنْهُ، وَيَقُولُ لَهُمُ ‏"‏ اذْكُرُوا اسْمَ اللَّهِ، وَلْيَأْكُلْ كُلُّ رَجُلٍ مِمَّا يَلِيهِ ‏"‏‏.‏ قَالَ حَتَّى تَصَدَّعُوا كُلُّهُمْ عَنْهَا، فَخَرَجَ مِنْهُمْ مَنْ خَرَجَ، وَبَقِيَ نَفَرٌ يَتَحَدَّثُونَ قَالَ وَجَعَلْتُ أَغْتَمُّ، ثُمَّ خَرَجَ النَّبِيُّ صلى الله عليه وسلم نَحْوَ الْحُجُرَاتِ، وَخَرَجْتُ فِي إِثْرِهِ فَقُلْتُ إِنَّهُمْ قَدْ ذَهَبُوا‏.‏ فَرَجَعَ فَدَخَلَ الْبَيْتَ، وَأَرْخَى السِّتْرَ، وَإِنِّي لَفِي الْحُجْرَةِ، وَهْوَ يَقُولُ ‏{‏يَا أَيُّهَا الَّذِينَ آمَنُوا لاَ تَدْخُلُوا بُيُوتَ النَّبِيِّ إِلاَّ أَنْ يُؤْذَنَ لَكُمْ إِلَى طَعَامٍ غَيْرَ نَاظِرِينَ إِنَاهُ وَلَكِنْ إِذَا دُعِيتُمْ فَادْخُلُوا فَإِذَا طَعِمْتُمْ فَانْتَشِرُوا وَلاَ مُسْتَأْنِسِينَ لِحَدِيثٍ إِنَّ ذَلِكُمْ كَانَ يُؤْذِي النَّبِيَّ فَيَسْتَحْيِي مِنْكُمْ وَاللَّهُ لاَ يَسْتَحْيِي مِنَ الْحَقِّ‏}‏‏.‏ قَالَ أَبُو عُثْمَانَ قَالَ أَنَسٌ إِنَّهُ خَدَمَ رَسُولَ اللَّهِ صلى الله عليه وسلم عَشْرَ سِنِينَ‏.‏
