*3.I will remove the "by" there. Is that OK with you? 
 *4.Do you really believe Sufism had been aroused as a movement and had been finalised in its philosophy, method, and doctrine only by the personal work of Uwais al-Qarni and/or Hasan Basri? Do you really believe that is possible to anyone today to find you the exact channels through which this esoteric influence had been exercised? By person or through writings? What we have is tons of studies saying that Sufism in its basic views, methodology and doctrine follows the typical views and logic of the neoplatonic doctrine, and that this is related to the presence of these neoplatonic philosophers in the area and specifically in the Sassanid court. And that its name, not roughly, but exactly means in their native language "wise men". This is what the refs given say this is what I input. I don't know anything else, I cannot contact an original research, and I don't have the calibre to contact the researchers and ask them what you asking me.  

 I am not trying to convey anything to the readers, I only find it strange to have so many old and modern *absolutely reliable and serious* studies explaining the neoplatonic roots of the movement and how these had been implemented, and in wp to have an article failing to mention the word neoplatonism even for a single time. To me is strange to see someone opposing to that by using every kind of excuses, first that is "convoluted", then that is grammatically imperfect, now asking questions that nobody today can really answer.  

 I never have discussed so much a single sentence in an article, and I never have input so many refs in one. I am indeed a little tired about it but not so as to accept the deletion of fully and multiple sourced text for just saving my self from a nightmare. Still waiting your answer about the text below which I believe is necessary as to explain to the reader what you also had ask, on what that influence was, in some detail.
