Sunan an-Nasa'i, Volume 6, Book 51, Hadith 5747 (DarusSalam) ⓘ
It was narrated from Sa'eed bin Al-Musayyib that: He disliked putting the dregs of Nabidh into (new) Nabidh lest it become strong because of the dregs.
أَخْبَرَنَا سُوَيْدٌ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ، عَنْ مَعْمَرٍ، عَنْ قَتَادَةَ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّهُ كَانَ يَكْرَهُ أَنْ يَجْعَلَ، نَطْلَ النَّبِيذِ فِي النَّبِيذِ لِيَشْتَدَّ بِالنَّطْلِ .
