Musnad Ahmad 181:1

Muhammad ibn Bakr al-Bursani narrated to us, he said: Abd al-Hamid ibn Ja'far informed us, he said: My father informed me, from Ziyad ibn Mina, from Abu Sa'id ibn Abi Fadala al-Ansari—and he was one of the Companions—that he said: I heard the Messenger of Allah, peace and blessings of Allah be upon him, saying: "When Allah, the Almighty and Majestic, gathers the first and the last for a Day about which there is no doubt, a caller will call out: 'Whoever associated anyone with Allah in a deed he performed for Him, let him seek his reward from someone other than Allah, the Almighty and Majestic, for Allah is the most independent of all partners from shirk (associating partners with Him).'"
