Shaykh Abdul Asis bin Abdillah bin Baz was asked about the Ikhwanul Muslimin in the Maganzine Al Majallah: (Issue No. 806, 2/25/1406H pg.24) What follows next is the text of the question and answer:
"Noble Shaykh, the movement of the Ikhwanul Muslimin entered into the Kingdom a while ago and has become very active amongst the students of knowledge. What is your view on this movement? And what is the extent of their conformity with the methodology of Ahlus Sunnah wal Jamaa'ah?"
The Shaykh replied:"The distinguished scholars have criticized the Ikhwanul Muslimin movement because they are not active in calling to the Oneness (Tawheed) of Allah or in forbidding Shirk and rejecting innovations. They have specific methods that they are deficient in such as a lack of enthusiasm for calling to Allah and a lack of directing their followers to the correct creed, which Ahlus Sunnah Wal Jamaa'ah are upon.
The Ikhwanul Muslimin must devote special attention to calling people to the way of the Salaf, which includes calling to the Oneness of Allah and to the rejection of grave-worship, devotion to the deceased, and asking help from the dead in the graves, such as Hasan, Husayn, Al-Badawee, and so on. The must focus on this fundamental principle, which is represented in Laa Ilaaha IllaaAllaah, the foundation of the Religion. The first thing that the Prophet SalaAllahu Alayhi Wa Sallam called to in Makkah was the Oneness (Tawheed) of Allah, i.e. the meaning of Laa Illaaha IllaaAllaah.
Many scholars criticize the Ikhwaan-ul-Muslmeen for this, i.e. their lack of being active in calling to Tawheed and to doing acts of worship sincerely for Him alone whilst rejecting the innovations of the ignorant such as being devoted to deceased individuals, asking for their help, making oaths to them, and presenting sacrificial offerings to them, which are all acts of Major Shirk. They also criticize them for their lack of concern for the Sunnah, following the Sunnah, and interest of the noble hadeeth and the religious rulings the Salaf of this ummah adhered to. There are many other things that I have heard the Ikhwaan being criticized for. We ask Allah to guide them to the truth."
