Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) used to pray the night prayer two (rak'ahs) by two, and when the morning drew near, he would perform witr with one (rak'ah), and he said: "Indeed Allah Almighty is One and loves what is one (odd)."
Imam al-Tabarani (may Allah have mercy on him) said: "Only al-Wassafi narrated this hadith from Atiyyah, from Abu Sa'id (may Allah be pleased with him), and it is narrated from Abu Sa'id (may Allah be pleased with him) only with this chain, whereas al-A'mash, Mis'ar and others narrated it from Sayyiduna Ibn Umar (may Allah be pleased with them both)."
