High Quality Content by WIKIPEDIA! There are two contemporary histories of Ibn 'Abd al-Wahhab and his religious movement from the point of view of his supporters: Ibn Ghannam's Rawdhat al-Afkar wal-Afham and Ibn Bishr's 'Unwan al-Majd fi Tarikh Najd. Ibn Ghannam, a native of al-Hasa who died in 1811, was the only historian to have observed the beginnings of Ibn 'Abd al-Wahhab's movement first-hand. His chronicle ends at the year 1797. Ibn Bishr's chronicle, which stops at the year 1854, was written a generation later than Ibn Ghannam's, but is considered valuable partly because Ibn Bishr was a native of Najd and because Ibn Bishr adds many details to Ibn Ghannam's account.
