حَدَّثَنَا وَكِيعٌ حَدَّثَنَا شُعْبَةُ عَنْ يَحْيَى بْنِ عُبَيْدٍ عَنِ ابْنِ عَبَّاسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ يُنْبَذُ لَهُ لَيْلَةَ الْخَمِيسِ فَيَشْرَبُهُ يَوْمَ الْخَمِيسِ وَيَوْمَ الْجُمُعَةِ قَالَ وَأُرَاهُ قَالَ وَيَوْمَ السَّبْتِ فَإِذَا كَانَ عِنْدَ الْعَصْرِ فَإِنْ بَقِيَ مِنْهُ شَيْءٌ سَقَاهُ الْخَدَمَ أَوْ أَمَرَ بِهِ فَأُهْرِيقَ
مسند امام احمد بن حنبل · Hadith 2068
It was narrated from Ibn 'Abbas that dates would be soaked for the Prophet (PBUH)on the night before Thursday, and he would drink it on Thursday and Friday. - [The narrator] said: And I think he said: on Saturday.Then when the time for 'Asr came, if any of it was left over, he would give it to the servants or order that it be poured away.
