Bukhari, the famous Iranian compiler of "al-Jame' as-Sahih"

On July 20,810 AD, Mohammad Ibn Ismail Ibn Ibrahim Ibn Bardizbah Bukhari, the famous Iranian compiler of hadith, from what came to be later regarded as Sunni sources, was born in Bukhara (presently in Uzbekistan) in a family which before conversion to Islam were Zoroastrian fire-worshippers.
His father, Ismail, was also known as a hadith scholar, and it seems that with a zeal that is associated with converts, he gave a weird fatwa (against the letter and spirit of the shari’ah), saying persons drinking the milk of the same cow are considered foster siblings and hence cannot marry among themselves!
This fatwa led to his expulsion from Bukhara and he soon died, leaving his son, an orphan, who on entering adolescent years started collecting hadith from anyone who could relate. In his late teens, he travelled to Mecca for pilgrimage, and after visiting the important centres of learning, exchanging information on hadith from at least 1,000 persons, and recording over 700,000 narrations, he returned to his hometown Bukhara after an absence of 16 years.
Here he compiled his "al-Jame' as-Sahih", which is known and revered as "Sahih Bukhari" by Sunni Muslims, and contains 7,275 hadith, which he selected as per his inclinations. It seems that because of the usurper Abbasid regime's intense watch on the Infallible Imams of the Ahl al-Bayt, Bukhari did not visit the rightful successors of Prophet Mohammad (SAWA) for precise information on authentic hadith. In 864 AD, he settled in Nishapur in Khorasan, where he met another Iranian with Sunni inclinations, named Muslim ibn Hajjaj, who became his student, and eventually collector of a separate book on hadith, known as "Sahih Muslim". Later he moved to Khartank, a village near Samarqand where he died in 870.
