عَنْ كَبْشَةَ بِنْتِ أَبِي مَرْيَمَ رَضِيَ اللَّهُ عَنْهَا قَالَتْ قُلْتُ لِأُمِّ سَلَمَةَ رَضِيَ اللَّهُ عَنْهَا أَخْبِرِينِي مَا نَهَى عَنْهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ أَهْلَهُ قَالَتْ نَهَانَا أَنْ نَعْجُمَ النَّوَى طَبْخًا وَأَنْ نَخْلِطَ الزَّبِيبَ وَالتَّمْرَ
It is narrated from Sayyida Kabsha bint Maryam (may Allah be pleased with her), she says: I asked Umm al-Mu'mineen Sayyida Umm Salamah (may Allah be pleased with her) to tell me about something from which the Noble Prophet (peace and blessings be upon him and his family) forbade his household. She said: The Prophet (peace and blessings be upon him and his family) forbade us from eating cooked date stones and from making nabidh by mixing dried dates and fresh dates together.
