Sahih Bukhari | Volume 9 | Hadith Number 521

Narrated by 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 Khuzaima 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)
