It is narrated from Hazrat Ma'ruf bin Wasil, he says that my mother told me about a woman who was called Bint al-Aq'as. And she was the daughter-in-law of Hazrat Abdullah bin Umar (may Allah be pleased with them). That she came to Hazrat Ibn Umar (may Allah be pleased with them) with a green-colored jug. Hazrat Ibn Umar (may Allah be pleased with them) asked, "What is this?" She replied, "We make nabidh in this jug." So Hazrat Ibn Umar (may Allah be pleased with them) put his hand inside the jug and then said: "I make you swear that you must certainly drink from it, because it is just like a bottle."
