Musnad Ahmad Hadith 19655

Affan narrated to us, Hammad ibn Salamah narrated to us, Ali ibn Zayd ibn Jud'an informed us, from Umara al-Qurashi, who said: We visited Umar ibn Abd al-Aziz, and among us was Abu Burdah. He fulfilled our needs, and when Abu Burdah left, he returned. Umar ibn Abd al-Aziz said: "I remember the shaykh." He said: "What brought you back? Did I not fulfill your needs?" Abu Burdah said: "Except for a hadith that my father narrated to me from the Prophet, peace and blessings be upon him, who said: 'Allah, Mighty and Majestic, will gather the nations on the Day of Resurrection,'" and he mentioned the hadith. Umar said to Abu Burdah: "By Allah, did you hear Abu Musa narrate it from the Prophet, peace and blessings be upon him?" He said: "Yes, I heard it from my father narrating it from the Messenger of Allah, peace and blessings be upon him."
