Sahih Muslim
حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، حَدَّثَنَا لَيْثٌ، عَنْ عَطَاءِ بْنِ أَبِي رَبَاحٍ، عَنْ جَابِرِ بْنِ عَبْدِ، اللَّهِ الأَنْصَارِيِّ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُ نَهَى أَنْ يُنْبَذَ التَّمْرُ وَالزَّبِيبُ جَمِيعًا وَنَهَى أَنْ يُنْبَذَ الرُّطَبُ وَالْبُسْرُ جَمِيعًا .
Jabir b. 'Abdullah al-Ansari reported that Allah's Messenger (ﷺ) prohibited the (preparation of) Nabidh by mixing together fresh dates and grapes, and he prohibited the preparation of Nabidh by mixing the fresh dates and unripe dates together.
