148 - Abdullah ibn Abd al-Jalil al-Basri narrated to us, he said: Abdullah ibn Nujay narrated to us, from Muhammad al-Kindi, he said: Ali ibn Abi Talib (may Allah be pleased with him) said: "If a drop of nabidh (fermented drink) containing dregs fell into a large vessel (hubb) of rainwater, the water in that vessel would become unlawful."

149 - Muhammad ibn Bahr narrated to us, he said: Abd al-A'la narrated to us, he said: Ibrahim ibn Yazid narrated to us, from Abdullah ibn Ubayd ibn Umayr, he said: "If a drop of wine fell into a jar filled with water, that water would become unlawful for its inhabitants to use."

• I said to Ishaq: "What about a piece of pitch (zaft) that was taken out of a skin containing wine; can it be used to plug cracks?" He said: "If the pitch is the predominant substance, there is no harm in it."

Chapter: Wine Poured into Vinegar

• I asked Ishaq again: "A cup of wine poured into a jar of vinegar?" He said: "He should not use it for seasoning immediately." It seemed he held the view that it should be left until the vinegar becomes strong, and he mentioned the hadith of Umar: "Eat from the wine what Allah has caused to spoil."

150 - Mahmud ibn Khalid narrated to us, he said: Umar ibn Abd al-Wahid narrated to us, he said: I heard al-Awza'i say—regarding a cup of wine thrown into vinegar—he said: "It should not be consumed in its place, but it should be left for the amount of time one perceives it would have changed had it not been placed into it; then it may be consumed, for it is in the position of wine when it is placed into murri (a type of fermented condiment)."
