The Messenger of Allah ﷺ came in to visit us, so we offered him butter and dates, for he loved butter and dates.
دخل علينا رسول الله ﷺ فقدمنا زبدا وتمرا، وكان يحب الزبد والتمر.
Abu Dawud (3837) and Ibn Majah (3334) narrated it through Ibn Jabir, who said, Salim bin Amir narrated to me, from the two sons of Busr, and they mentioned it. Its chain is sahih. Ibn Jabir is Abdul-Rahman bin Yazid bin Jabir al-Shami, and the two sons of Busr are Abdullah and Atiya, both companions.On this subject there is also a report from Ismail bin Abu Khalid, from his father, who said, "I came upon a man who was eating dates with milk, and he said, 'Come closer, for the Messenger of Allah ﷺ called this the two finest things.'"Ahmad (15893) narrated it from Waki, who said, Ismail bin Abu Khalid narrated to us, from his father, and he mentioned it. In its chain is Abu Khalid al-Ahmasi al-Bajali, who was reported from solely by his son Ismail, and no one deemed him reliable except Ibn Hibban. For this reason al-Hafiz said, "Acceptable," meaning when corroborated, and I know of no corroboration for him.So Haythami's statement in Majma (5/41), "Ahmad narrated it, and its narrators are the narrators of al-Sahih, except for his father, and he is reliable," rests on his reliance on Ibn Hibban's attestation of reliability, as has been noted repeatedly.As for his saying, "and he was eating tajammu," tajammu and majj mean eating dates with milk, which is to take a sip of milk and follow it with a date.As for what was narrated from Yusuf bin Abdullah bin Salam, who said, "I saw the Prophet ﷺ take a piece of barley bread, place a date on it, and say, 'This is a condiment for this,'" it is daif. Abu Dawud (3830) and Tirmidhi in al-Shamail (185) narrated it through Umar bin Hafs, who said, my father narrated to us, from Muhammad bin Abu Yahya, from Yazid al-Awar, from Yusuf bin Abdullah bin Salam, who mentioned it. Its chain is daif due to the obscurity of Yazid, who is Ibn Abu Umaya al-Awar.
