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.

When were the hadiths written down?

Hadith were eventually written down, evaluated and gathered into large collections mostly during the reign of Umar II (bin Abdul Aziz, grandson of Umar bin Khattab(RAA)2nd Caliph) during 8th century, and also in the 9th century. These works are referred to in matters of Islamic law and History to this day.

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.
