The Difference Between the Call of Shaykh Muhammad ibn 'Abd al-Wahhab and Contemporary Calls

Question:
This is a question asking about Shaykh Muhammad ibn 'Abd al-Wahhab (may Allah have mercy on him). Or between the call of Shaykh Muhammad ibn 'Abd al-Wahhab (may Allah have mercy on him) and other contemporary calls, especially what is called the Da'ish organization, the Muslim Brotherhood, and al-Nusrah. This is because some people attribute these deviant calls to the call of Shaykh Muhammad ibn 'Abd al-Wahhab. So what is the truth in this matter?

Answer:
The call of Shaykh Muhammad ibn 'Abd al-Wahhab began in the twelfth century, and nothing but good came from it. The people only knew it as good. These new movements came late, and they are not attributed to the Shaykh's call. The Shaykh's call is a call of reform and a call of good, so these matters are not attributed to it. The Shaykh warns against such matters in his call. May Allah bless the Shaykh in his call.
The lands of Najd, before his arrival and before his call, had a ruler in every town and every village. They did not submit to the ruler of the neighboring town. When this call came, Allah gathered these lands under one imam, from one end to the other, and they became one country instead of being scattered and lost.
Also, this call bore fruit; it produced a great deal of scholarly output. These beneficial books written by the scholars of this call are all fruits of this blessed call. So it bore fruit and produced, praise be to Allah. Yes.
