Ṣaḥīḥ al-Bukhārī (Arabic: صحيح البخاري‎), is one of the six canonical hadith collections (Al-Kutub Al-Sittah) of sunni Islam. These prophetic traditions, or hadith, were collected by the Persian Muslim scholar Muhammad ibn Ismail al-Bukhari, after being transmitted orally for generations. Sunni Muslims view this as one of the three most trusted collections of hadith along with Sahih Muslim and al-Muwatta . In some circles, it is considered the most authentic book after the Qur'an. The Arabic word sahih translates as authentic or correct.

The actual title of the book commonly referred to as Sahih al-Bukhari, according to Ibn al-Salah, is: al-Jaami’ al-Sahih al-Musnad al-Mukhtasar min Umur Rasool Allah wa sunanihi wa Ayyamihi. A word for word translation is: The Abridged Collection of Authentic Hadith with Connected Chains regarding Matters Pertaining to the Prophet, His practices and His Times.Ibn Hajar al-Asqalani mentioned the same title replacing the word umur, matters, with hadith.

Abu Bakr (Abdullah ibn Abi Quhafa) (Arabic: عبد الله بن أبي قحافة, Transliteration: ʿAbd Allāh ibn Abī Quḥāfah, c. 573 CE - 634 CE) also known as Abū Bakr as-Șiddīq (Arabic: أبو بكر الصديق) was a senior companion (Sahabi) and the father-in-law of the Islamic prophet Muhammad. He ruled over the Rashidun Caliphate from 632–634 CE when he became the first Muslim Caliph following Muhammad's death. As Caliph, Abu Bakr succeeded to the political and administrative functions previously exercised by Muhammad, since the religious function and authority of prophethood ended with Muhammad's death according to Islam. He was called Al-Siddiq (The Truthful) and was known by that title among later generations of Muslims.

As a young man, Abu Bakr became a cloth merchant and he traveled extensively in Arabia and neighboring lands in the Middle East, through which he gained both wealth and experience. He eventually came to be recognized as the chief of his clan. On his return from a business trip to Yemen, he was informed that in his absence Muhammad had openly declared his prophethood. Not long after, Abu Bakr accepted Islam and was the first person outside the family of Muhammad to openly become a Muslim. He was instrumental in the conversion of many people to the Islamic faith and early in 623, Abu Bakr's daughter Aisha was married to Muhammad, strengthening the ties between the two men.
