There's a Hadith that Prophet once blessed and prayed for one of the Sahaba when he corrected Prophet for missing a line from the Qur'an. I can't recall the exact version of it.

The point is that it goes to show that even Prophet himself had a proven tendency to forget lines from the Qur'an. This is a recorded version, we don't know how many more from himself and others.
