You should meet the Madkhali Salafis. I think you would get along with them on thiis .
I just found there website. Calling Sayyid al-Qutb a Leninist is a tad over the top don't you think? Let's just say we agree that Sayyid al-Qutb, Mawdudi, along with al-Qa'ida, etc. are Neo-Kharijites though as far as i know there are no historical connections between them and the Kharijites.
However Sayyid Qutb is loved by the Rawafid, on of the reasons was his attacks on Imam Mu3wiyya (as) which i heard some bahai consider him the beast of revelation.
I hardly think that would be enough for a Shi'ite to make common cause with him! Who, after all, really likes Muawiyyih? As for his being the Beast of Revelation, my recollection is that Abdu'l-Baha applies this to the Umayyyads as a whole, not a specific individual.
I do understand that Sayyid al-Qutb did attempt to establish relations with Ayatollah Kashani back in the fifties. I don't know if Kashani responded favorably, but I wouldn't put it past him. Kashani did whatever was expedient, first supporting Mossadeq against the Shah, then working with the CIA and the British to get rid of him! Kashani, along with Falsafi led the persecution against Baha'is in the 1950's.
He also wrote on wahdat ul wujood.
Positively or negatively?
Puzzled why his theology bothered you. Maybe it was the political part.
Isn't that the main part?
Not the Ibn Arabi kind of sufism

? I think some bahai consider him the greatest mystic and philosopher.
Most Persian Baha'is I know would assign Rumi that station. As for western Baha'is, these are mostly just names to them. As for philosophy, many of them (again, Persian Baha'is or Baha'is academics) are attracted to thinking of the Ishraqiyyun school, although I wrote a major paper discussing the distinction between Baha'u'llah's thought and Ishraqi philosophy. Personally, I find Ibn Arabi's theosophy gets to close to pantheism for my comfort. I have the same problem with the sacramental mysticism of Meister Eckhart.
