al-Nogaidan studied principles of Sharia science by classical Islamic way under the guidance of scholars in his city Buraidah from 1985 to 1991.
In mid-1991, along with a group of jihadists, al-Nogaidan took a part in burning video shops in the capital Riyadh; as a result he was sentenced for two years and eight months in prison.
al-Nogaidan's ideological transformation started in the mid-nineties when he been introduced to the heritage of Islamic rationalists and writings of contemporary Muslim thinkers from Morocco and Jordan.
[4] In 1999, al-Nogaidan published his first article which highlighted the dispute between the Hadith School "rigid followers of Prophet Mohammed preaching" and the Aqel school "followers of more flexible interpretation of Prophet Mohammed preaching" in the early period of Islamic civilization.
The thoughts and arguments against the classical concept of Wahabbism raised concern among clerics of Saudi Arabia; consequently, al-Nogaidan was sentenced for 75 lashes[7] and worse gained a fatwa of blasphemy and call for waste of blood or announcement of his repentance publicly.
