It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that he asked: In your view, which was the last recitation (in the course of the revelation of the Qur'an)? The people said: The recitation of Zayd bin Thabit. He said: No! Rather, the Messenger of Allah (peace and blessings be upon him) used to review the Qur'an with (present it to) Jibril (peace be upon him) every year, and in the year in which he (peace and blessings be upon him) passed away, he reviewed it twice. So the recitation of Abdullah bin Mas'ud was the very last recitation. This hadith has an authentic chain (sahih al-isnad), but the two Shaykhs (Bukhari and Muslim) did not record it with this wording, and the scholarly benefit of this hadith is the special mention of Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him).
