Philosophers like Ibn Sina and Ibn Sab'in and their ilk from the Mu'tazila, and their emptiness of the creed that the Imams of knowledge and religion from the Ahl al-Sunnah wa al-Jama'ah, the people of Hadith, Fiqh, Sufism, Kalam, and others from the followers of the four Imams, mention. For all of these agree that Allah Almighty is alive, knowing with knowledge, capable with power.
The text does not mention the affirmation of the vision of Allah Almighty, and Allah Almighty has affirmed the vision for Himself in a way that leaves no room for doubt about it.
The text does not mention faith in the message of the Prophet (peace be upon him), nor in the Last Day, nor in what the Prophet (peace be upon him) informed about the people of major sins. These are matters on which Muslims have agreed, and scholars have become accustomed to mentioning them in concise creeds. As for Al-Murshida, it did not contain anything of that.
As for what is mentioned in its introduction, that it is obligatory for every Muslim to know what is in it, and the Imams have agreed that what is obligatory for Muslims is what Allah and His Messenger have made obligatory. And no one has the right to make obligatory what is mentioned in it, such as the saying that Allah is capable of whatever He wills. And the creed of Muslims is that Allah is capable of all things, whether He wills it or not.
Based on these considerations, there is no need for any Muslim to learn or read it. And it is not permissible for anyone to deviate from what is in the Book and the Sunnah, and what the predecessors and Imams of the Ummah have agreed upon, to what some people have innovated which may contain the opposite. And no one has the right to establish a creed or worship for people from himself, but rather he must follow and not innovate.
And despite the truth in some of these considerations, such as what the apparent Al-Murshida suggests by negating the attributes, and such as neglecting what relates to prophethood and the Last Day, Ibn Taymiyyah's critique of the book.
See: Ibn Taymiyyah, Majmu' al-Fatawa, p. 224 onwards. He mentioned that he authored a large book refuting Al-Mahdi, pp. 476-402.
