"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). (Using translation from Nasāʾī 5746)
لِأَنَّهَا تُرِكَتْ حَتَّى صُفِّيَ صَفْوُهَا وَبَقِيَ كَدَرُهَا وَكَانَ يَكْرَهُ كُلَّ شَيْءٍ يُنْبَذُ عَلَى عَكَرٍ»
