The Shoebats went on to cite two papers written by Khan in 1983 and 1984 pertaining to the Organization of Petroleum Exporting Countries, or OPEC, described as "an intergovernmental oil company consisting of mainly Islamic countries" and a second titled "Juristic Classification of Islamic Law" (both of which were written prior to the family's move to the United States).
With respect to the latter,
Shoebat bracketed a not-present "Sharia" in the title and included a snapshot of the only
page of the paper freely available (which in no part suggested support for Sharia law or membership in the Muslim brotherhood and appeared to be an academic piece, not an advocacy paper). The Shoebats maintained that in the paper "Khan shows his appreciation for the icon of the Muslim Brotherhood," referencing a citation holding that "The contribution to this article of S. Ramadan’s writing is greatly acknowledged."
However, the quoted text was suspiciously elided from the screenshot that appeared on
Shoebat and looked far less damning in its actual context as an academic footnote:

The elided citation was offered as support of the assertion that Khan's work was undersigned by the "Saudi Wahhabist religious institution" and cited a "recent report" that Khan had moved from Pakistan to the United Arab Emirates, "a hotbed for the Muslim Brotherhood."
