Narrated Aisha: The Prophet heard a man reciting the Qur'an in the mosque and said, "May Allah bestow His Mercy on him, as he has reminded me of such-and-such verses of such a Surah." (Sahih al-Bukhari: vol. 6, bk. 61, no. 556; also Sahih Muslim: bk. 4, no. 1720)
Narrated Abdullah ibn Mas'ud: ... (Muhammad said) I am only a human being and I forget just as you do; so when I forget, remind me ... (Sunan Abu Dawud: bk. 3, no. 1015; also Sahih al-Bukhari: vol. 1, bk. 8, no. 394)

Ibn Masud & Umar Ibn Kaib, two of the four men Muhammed told people to learn the Quran from, both disputed about the number of Sura's in the Quran. Masud's Quran didn't have chapters 1, 113 or 114, and kaib's Quran had two extra Suras - a total of 116.
