In the 3rd century of Islam (from 225/840 to about 275/889), hadith experts composed brief works recording a selection of about two- to five-thousand such texts which they felt to have been most soundly documented or most widely referred to in the Muslim scholarly community.

In which era did the compilation of the hadith began?

The most revered of all traditionalists was al-Bukhārī (ah 194–256 [810–870 ce]), whose Al-Jāmiʿ al-ṣaḥīḥ (“The Authentic Collection”) has a unique place in the awe and esteem of Muslims as a work of great historical import and deep piety.

How long was the Hadith written after Muhammad?

It was the first work of its kind exclusively dedicated to hadiths, and is the most authoritative of the so-called Six Books—canonical collections that were written down some 200 years after the death of Prophet Muhammad.
