Musnad Abu Ya'la al-Mawsili 95:5

'Amr ibn Muhammad al-Naqid said: Abu Salamah al-Khuza'i narrated to us that Ja'far ibn Burqan narrated to them in this hadith that Salim ibn Wabisa led them in prayer in al-Raqqah, and he mentioned this hadith of Wabisa. And Wabisa said: "We bear witness against you just as it was witnessed against us, so you have retained [it], and we are conveying it to you."
