Hadith 8:914
Abu Bakr narrated to us, he said: Ubayd Allah ibn Musa narrated to us, from Hanzala, who said: I asked al-Qasim about the prayer with the Imam at Arafat. He said: "Pray with his prayer." I said: "I am a Meccan." He said: "I have known." He said: And I asked Salim and Tawus, and they both said the like of that.
