Amr bin Dinar narrates: A man came to Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) and said: "Ibn al-Zubayr says that breastfeeding of one suck or two sucks does not establish prohibition." Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: "The judgement of Allah and His Messenger is better than the judgement of Ibn al-Zubayr. Breastfeeding, whether little or much, has the same status."
Al-Tabarani recorded it; its chain contains a narrator, Ibrahim bin Yazid al-Khuzi, who is matruk (abandoned).
