Masruq narrates: Sayyiduna Abdullah (may Allah be pleased with him) came with an udder and began eating from it. He said to those present: "Come forward." So the people came forward, but one man among them drew back. Sayyiduna Abdullah (may Allah be pleased with him) said: "What is the matter with you?" He replied: "I have made the udder unlawful for myself." Sayyiduna Abdullah (may Allah be pleased with him) said: "This is one of the whisperings of Satan. Come forward, eat, and make expiation for your oath." Then he recited this verse: "O you who believe, do not make unlawful the good things that Allah Almighty has made lawful for you."
Al-Tabarani recorded it in al-Mu'jam al-Kabir, and its narrators are the narrators of the Sahih.
Abu al-Bakhtari narrates: There was a quarrel between a man from among the companions of Sayyiduna Abdullah (may Allah be pleased with him) and his wife. The woman said: "The only condiment for you and your children comes from my goat's milk." The man swore that he would not eat anything of that goat's milk. Then a guest came to them, and the woman (in keeping with what she had said) prepared a condiment for them from her goat's milk. The man said: "You know that I will not eat it." The woman said: "By Allah, if you do not eat it, I will not eat it either." The guest said: "By Allah, if the two of you do not eat it, I will not eat it either." So the two of them spent the night without supper. The next day Sayyiduna Abdullah (may Allah be pleased with him) was told about it. The man came to Sayyiduna Abdullah (may Allah be pleased with him), and Sayyiduna Abdullah (may Allah be pleased with him) said: "What is it that has come between you and your wife?" He said: "It is neither divorce, nor zihar, nor ila'." Then he related the whole incident. Sayyiduna Abdullah (may Allah be pleased with him) said: "I adjure you that when you return to your wife, the first thing you do is to eat the condiment made from this goat's milk. And I think that if your mind is not at ease, you should make expiation (for your oath)."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains Ata bin al-Sa'ib, whose memory became confused (ikhtilat), but he is thiqah (trustworthy), and the rest of its narrators are the narrators of the Sahih.
