(56) باب ذِكْرِ مَا يَجُوزُ شُرْبُهُ مِنَ الأَنْبِذَةِ وَمَا لاَ يَجُوزُ
It was narrated that Sa'eed bin Al-Musayyab said:
"Khamr is so called because it is left until the good parts are gone and the dregs remain." And he disliked everything that was made by using dregs (by adding new materials to the dregs).
