Abu Usaid As-Sa'di invited Messenger of Allah ﷺ to his wedding party and his wife who was the bride, served them on that day. Do you know what drink she gave Messenger of Allah ﷺ? She had soaked some dates for him (in water) overnight, and when he had finished his meal she gave him that drink (of soaked dates).  

دَعَا أَبُو أُسَيْدٍ السَّاعِدِيُّ رَسُولَ اللَّهِ ﷺ فِي عُرْسِهِ وَكَانَتِ امْرَأَتُهُ يَوْمَئِذٍ خَادِمَهُمْ وَهْىَ الْعَرُوسُ قَالَ سَهْلٌ تَدْرُونَ مَا سَقَتْ رَسُولَ اللَّهِ ﷺ أَنْقَعَتْ لَهُ تَمَرَاتٍ مِنَ اللَّيْلِ فَلَمَّا أَكَلَ سَقَتْهُ إِيَّاهُ  

When Abu Usaid As-Saʿidi got married, he invited the Prophet ﷺ and his companions. None prepared the food for them and brought it to them but his wife. She soaked some dates in water in a stone pot overnight, and when the Prophet ﷺ had finished his food, she provided him with that drink (of soaked dates).  

لَمَّا عَرَّسَ أَبُو أُسَيْدٍ السَّاعِدِيُّ دَعَا النَّبِيَّ ﷺ وَأَصْحَابَهُ فَمَا صَنَعَ لَهُمْ طَعَامًا وَلاَ قَرَّبَهُ إِلَيْهِمْ إِلاَّ امْرَأَتُهُ أُمُّ أُسَيْدٍ بَلَّتْ تَمَرَاتٍ فِي تَوْرٍ مِنْ حِجَارَةٍ مِنَ اللَّيْلِ فَلَمَّا فَرَغَ النَّبِيُّ ﷺ مِنَ الطَّعَامِ أَمَاثَتْهُ لَهُ فَسَقَتْهُ تُتْحِفُهُ بِذَلِكَ  

An Arab lady was mentioned to the Prophet ﷺ so he asked Abu Usaid As-Saʿidi to send for her, and he sent for her and she came and stayed in the castle of Bani Saʿida. The Prophet ﷺ came out and went to her and entered upon her. Behold, it was a lady sitting with a drooping head. When the Prophet ﷺ spoke to her, she said, "I seek refuge with Allah from you." He said, "I grant you refuge from me." They said to her, "Do you know who this is?" She said, "No." They said, "This is Messenger of Allah ﷺ who has come to command your hand in marriage." She said, "I am very unlucky to lose this chance." Then the Prophet and his companions went towards the shed of Bani Saʿida and sat there. Then he said, "Give us water, O Sahl!" So I took out this drinking bowl and gave them water in it. The sub-narrator added: Sahl took out for us that very drinking bowl and we all drank from it. Later on ʿUmar bin ʿAbdul ʿAziz requested Sahl to give it to him as a present, and he gave it to him as a present.  

ذُكِرَ لِلنَّبِيِّ ﷺ امْرَأَةٌ مِنَ الْعَرَبِ فَأَمَرَ أَبَا أُسَيْدٍ السَّاعِدِيَّ أَنْ يُرْسِلَ إِلَيْهَا فَأَرْسَلَ إِلَيْهَا فَقَدِمَتْ فَنَزَلَتْ فِي أُجُمِ بَنِي سَاعِدَةَ فَخَرَجَ النَّبِيُّ ﷺ حَتَّى جَاءَهَا فَدَخَلَ عَلَيْهَا فَإِذَا امْرَأَةٌ مُنَكِّسَةٌ رَأْسَهَا فَلَمَّا كَلَّمَهَا النَّبِيُّ ﷺ قَالَتْ أَعُوذُ بِاللَّهِ مِنْكَ فَقَالَ قَدْ أَعَذْتُكِ مِنِّي فَقَالُوا لَهَا أَتَدْرِينَ مَنْ هَذَا قَالَتْ لاَ قَالُوا هَذَا رَسُولُ اللَّهِ ﷺ جَاءَ لِيَخْطُبَكِ قَالَتْ كُنْتُ أَنَا أَشْقَى مِنْ ذَلِكَ فَأَقْبَلَ النَّبِيُّ ﷺ يَوْمَئِذٍ حَتَّى جَلَسَ فِي سَقِيفَةِ بَنِي سَاعِدَةَ هُوَ وَأَصْحَابُهُ ثُمَّ قَالَ اسْقِنَا يَا سَهْلُ فَخَرَجْتُ لَهُمْ بِهَذَا الْقَدَحِ فَأَسْقَيْتُهُمْ فِيهِ فَأَخْرَجَ لَنَا سَهْلٌ ذَلِكَ الْقَدَحَ فَشَرِبْنَا مِنْهُ قَالَ ثُمَّ اسْتَوْهَبَهُ عُمَرُ بْنُ عَبْدِ الْعَزِيزِ بَعْدَ ذَلِكَ فَوَهَبَهُ لَهُ
