Narrated Anas: The Prophet (ﷺ) halted to consummate his marriage with Safiyya. I invited the Muslims to his wedding banquet. He ordered that leather dining sheets be spread. Then dates, dried yoghurt and butter were put on those sheets. Anas added: The Prophet (ﷺ) consummated his marriage with Safiyya (during a journey) whereupon Hais (sweet dish) was served on a leather dining sheet.

حَدَّثَنَا ابْنُ أَبِي مَرْيَمَ، أَخْبَرَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، أَخْبَرَنِي حُمَيْدٌ، أَنَّهُ سَمِعَ أَنَسًا، يَقُولُ قَامَ النَّبِيُّ صلى الله عليه وسلم يَبْنِي بِصَفِيَّةَ فَدَعَوْتُ الْمُسْلِمِينَ إِلَى وَلِيمَتِهِ أَمَرَ بِالأَنْطَاعِ فَبُسِطَتْ فَأُلْقِيَ عَلَيْهَا التَّمْرُ وَالأَقِطُ وَالسَّمْنُ. وَقَالَ عَمْرٌو عَنْ أَنَسٍ بَنَى بِهَا النَّبِيُّ صلى الله عليه وسلم ثُمَّ صَنَعَ حَيْسًا فِي نِطَعٍ.
