From Sahih Bukhari (Hadith 7425):
Narrated Zaid bin Thabit:Abu Bakr sent for me, so I collected the Qur'an till I found the last part of Surat-at-Tauba with Abi Khuza`ima Al-Ansari and did not find it with anybody else. (The Verses are): -- 'Verily, there has come to you an Apostle (Muhammad) from amongst yourselves..(till the end of Surat Bara'a) (i.e., at- Tauba).' (9.128-129) Yunus also narrated as above
