Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him) narrates from the Prophet (peace and blessings be upon him) that he was asked about the even and the odd. He (peace and blessings be upon him) said: "Two days and a night: the Day of Arafah and the Day of Sacrifice, and the odd means the Night of Sacrifice, which is the night of Muzdalifah."
Tabarani recorded it within a long hadith; it contains a narrator, Wasil bin al-Sa'ib, who is matruk (abandoned).
