It is narrated from Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him) that he prayed with the Messenger of Allah (peace and blessings be upon him) at Muzdalifah three rak'ahs of Maghrib and two rak'ahs of Isha; both prayers were offered together with one adhan and one iqamah.
This is how Jabir al-Ju'fi narrated it, and Jabir is not used as evidence.
