He is considered one of the most prominent and important scholars of hadith, and the author of the book "Sahih al-Bukhari", which was said to be "the truest book after the Holy Qur'an", distinguished by his scientific approach in dealing with the hadiths of the Prophet, and did not concern himself except with the correct ones.

He is Muhammad bin Ismail Al-Bukhari, who was born in Bukhara in 194 AH, of Persian origins. His book "Sahih al-Bukhari", which is said to be the truest book after the Qur'an, was compiled in 16 years, during which he traveled between Iraq, the Hijaz, the Levant and Egypt, so he did not reside in a city except enough to collect the hadiths of the Prophet from the breasts of its scholars.

The book "Sahih al-Bukhari" includes 7,600 hadiths that he chose after sifting 1080,7 hadiths, and his book was deposited only with what was true with him and reassured him himself. Those whom Bukhari heard directly about numbered <>,<>. The total number of narrators mentioned in Sahih al-Bukhari is more than <>,<>.

Imam al-Bukhari remained until his death one of the greatest keepers of the two officers. A story was told about him in this regard, as al-Bukhari came to Baghdad and heard from his introduction several sheikhs from the people of hadith, so they arranged a council for him, and conspired to test his discipline.

When Imam al-Bukhari settled in the council, one of them took the initiative and began to give him a hadith after a hadith, and al-Bukhari says after each hadith: I do not know him. Until 10 hadiths were completed with their chains of support.

Then another man in the council confronted him, and he did as the first did. 10 men followed him, each of whom narrated 10 hadiths, whose chains of transmission and text were mixed, and al-Bukhari did not know a single hadith.

When Imam al-Bukhari forgot that the people had emptied what was in their possession, he began to narrate their hadiths to them, one by one, correcting the hadith, and we died and supported it, until he came to the 100, and the people handed him over to him with precision and accuracy.

Bukhari's genius is exemplified in his scientific method. He chose 7,600 hadiths out of 90,<>; that is, he accepted a hadith and rejected <> hadiths. It has been said, among other things, "A hadith that Muhammad ibn Isma'il al-Bukhari does not know. Not talking."

Bukhari did not concern himself, except with authentic hadiths. He was a scholar of wound and modification. He taught men, "We do not judge a narrator as just unless there are 5 qualities in him: to be a sane adult Muslim who did not know about immorality and was not afflicted with the evil of virility." The latter means that one should not act irrelevantly from the dignity of the scientists.

When the disciple of al-Bukhari Muslim ibn al-Hajjaj al-Qushayri produced his saheeh, the highest degree of authenticity became that the hadith was mentioned in both saheehs or as it is said "reported by the two sheikhs".

The most powerful authentic hadith reported by the two sheikhs is the one narrated by many people about the creation of many raised to the Prophet (peace and blessings of Allaah be upon him).

The first hadith in Sahih al-Bukhari is "Actions are based on intentions, but everyone has what he intended." The Messenger of Allah (peace and blessings of Allaah be upon him) was right.

It is forbidden to write hadith

It is noteworthy that the Prophet (peace and blessings of Allaah be upon him) forbade writing hadith in his time, hating to mix with the Holy Qur'an, and did not forbid transmitting his words orally, and the correct hadith came: "Do not write about me other than the Qur'an, and whoever writes about me other than the Qur'an, let him erase it."

The codification of hadith began only in the year 100 AH, and 50 years later the hadiths began to be collected in books, and since the beginning of people's work in hadith, there were two ways to classify it, according to the topics, and according to the narrators.

Among those who compiled the hadith, according to his narrators, was Imam Ahmad ibn Hanbal in his famous Musnad, which included more than 26,<> hadiths. Ahmad devoted to each companion a chapter containing the hadiths he narrated.
