Prophet Mohammad(pbuh) forgot the verses of Quran

Prophet Mohammad pbuh forgot the verse of Quran 1

URDU TRANSLATION:

009 Prophet Mohammadpbuh forgot the verses of Quran

We know that in Bukhari Umar bin Khattab also claimed that the verse of Rajam is missing from the Quran.

Prophet Mohammad pbuh forgot the verse of Quran 2 

By the way, what guarantee does our Sunni fellows have to prove that there is no other verse is missing from Quran?

Please read Surah Qayamah (75:16-17)

"(Muhammad), do not move your tongue too quickly to recite the Quran. We shall be responsible for its collection and its recitation."

Allah(swt) gives guarantee that "we are reponsible for its recitation and collection" But Bukhari tells us a different story.
