Who are the Tablighi Jamaat and the Muslim Brotherhood?

Question:
May Allah reward you, Honorable Shaykh. This questioner was harsh with us in his question, saying: "I swear by Allah, I will complain to my Lord on the Day of Resurrection about your concealment of this from me. I hope you will graciously and commandingly put this question to the Shaykh, as my confusion in it is excessive. There is no power but in Allah. May Allah hear us in the best way. Yes. Do we continue with something? He says: I hope, I hope, and I hope that you will raise it. I hope, I hope that you will raise it. Yes, in good, if Allah wills. We have it. If we know the answer, we will answer; otherwise, we will say, Allah knows best. Yes. He says: We have a teacher who says that he is a Salafi, and that the Tablighi Jamaat are innovators, and that the Muslim Brotherhood, Sayyid Qutb, and Tariq al-Suwaidan are misguided innovators, and that they are from the Muslim Brotherhood. He says: Who are the Muslim Brotherhood? Who are the Salafis? Who are the Tablighi Jamaat? Clarify this for me, O our Shaykh, for my confusion has increased and I have doubted in my religion, in my righteous colleagues, and in our scholars. Is his statement correct?

Answer:
There are books, my brother. There are books written that clarify who the Muslim Brotherhood are and what their methodology is. There are books that clarify who the Tablighi Jamaat are and what their methodology is. Seek them out in the markets and read them, and you will know them, if Allah wills. You will know who the Tablighi Jamaat are and what their methodology is. And you will know who the Muslim Brotherhood are and what their methodology is.
As for the Salafis, they are those who are upon the methodology of the Salaf al-Salih (the earliest generations). He is called a Salafi (a follower of the Salaf) if he is truly upon their methodology, not merely by affiliation or claim, but truly upon their methodology. This is the Salafi.
There are specific books, yes. There are books about the Tablighi Jamaat. A book by Muhammad Aslam (may Allah have mercy on him), the Pakistani caller to Islam, and a book by Taki al-Din al-Hilali, the Moroccan, and a book by Shaykh Hamud ibn 'Abdullah al-Tuwajiri (may Allah have mercy on him) about the Tablighi Jamaat and their methodology. Writings have been written about them.
There are also writings about the Muslim Brotherhood that clarify their methodology, including their own books. Read from their books and you will know their call, their methodology, and what they are upon. The writings of al-Banna, his memoirs. The writings of Sayyid Qutb, especially Milestones. He is the one who wrote this and clarified his methodology. And those who responded to them, you will know what the errors are that they have from the books that responded to them, and they are many. Yes.
