Arabian peninsula travels
At age of sixteen, he, together with his brother and widowed mother made the
pilgrimage to Mecca. From there he made a series of travels in order to increase his knowledge of hadith. He went through all the important centres of Islamic learning of his time, talked to scholars and exchanged information on hadith. It is recorded that he stayed at
Basrah for four or five years, and in the
Hijaz for six; while he travelled to
Egypt twice and to
Kufah and
Baghdad many times.
When the authorities in Basrah received information of his arrival, they fixed a time for him to deliver a lecture. At the lecture, he was able to confine himself only to such Hadith as he had received on the authority of the early Hadith scholars of Basrah, and had nonetheless been unknown to the audience.
While in Baghdad, he was tested by ten Hadith scholars. They changed the
Isnad and text of one hundred hadith, and asked Bukhari about them during a public meeting. He said that he was not familiar with those hadith, recited the un-changed versions and said that they had probably inadvertently recited them wrongly. This was repeated by four hundred scholars in
Samarkand.
