A thoughtful comment from fellow reader:
perhaps we can understand the concept of hijab as an ontological marker for the necessity of a medium to negotiate the relationship between a cause and its effects
1) when it comes to Allah, the divine nur muhammadi negotiates between the singular limitless cause and His multiple, limited effects. Hence Muhammad is the Hijab of Allah. Because Allah's essence cannot be perceived, His actions- that is His direct effect (the Ahlul Bayt) negotiate and make possible the rest of mankind's perception of Him such that their purpose of existence can be fulfilled.
2) regarding the female's hijab- perhaps the veil is a marker for the medium of the womb which negotiates contact between the female and the rest of society- where her relationship with society is determined by their contact with her womb (either as offspring or progenitors) - haven't really thought this one out clearly yet.
3) regarding fatima al-zahra: her manifestation on earth as a unique ontological category of hawra al Insiyyah negotiates between her unknowable essence and her tangible and perceivable Worldly effects.
god is not rejecting that Torah was revealed all at once .
And those who disbelieve say, "Why was the Qur'an not revealed to him all at once?" Thus [it is] that We may strengthen thereby your heart. And We have spaced it distinctly.
The Prophet (peace and blessings be upon him) says: "The Torah, the Gospel, and the Zaboor, all were revealed in tablets and papers."

as yourself said, it’s a “claim”, that can not be verified ! re-written a millennium years after Moses by rabbis, and more than that: it’s false!
God does not talk with anyone directly !
And it is not for any human being that Allah should speak to him except by revelation or from behind a partition or that He sends a messenger to reveal, by His permission, what He wills. Indeed, He is Most High and Wise.
WhiIe in the USA, Monday 29May17 is Memorial Day, in Europe, Sunday 28 May 2017 is a Memorable Day; the day German Chancellor Angela Merkel pronounced a new vision for Europe:
Europe First and an implied "Make Europe Great Again". An equivalent to the Trump "America First" and "Make America Great Again"
While announced in a speech before a CDU [Christian Democrat Union] gathering in a tent, this is no circus from Bavaria. The European Union must now act primarily in its own interest without the UK because of Brexit and without the USA, Merkel proclaimed. A new future that must be willing to accept Russia and -l think- by extension China's "Belt and Road". http://www.mcclatchydc.com/news/politics-government/national-politics/article153130904.html entitled "Merkel: Europe must stay united in the face of ally uncertainty"; and, http://www.dw.com/en/merkel-europe-can-no-longer-rely-on-us-and-britian/a-39018097 The video will show the animosity, angst and acceptance associated with this new Europe First vision.
For an article with anti-Trump subtext, Chicago Tribune, 28May17, "Following Trump's trip, Merkel says Europe can't rely on U.S. anymore"; http://www.chicagotribune.com/news/nationworld/politics Search title for article.
CNN 2353hrs 28May17 posted a video of Merkel's speech.

To flesh-out the probable results of this Europe First vision in relation to the pipeline politics and objectives of our time, we can envision a Europe-Belt-and-Road (excluding the Ukraine and maybe also Turkey) and will include a Khoramshar-Karbala-with-or-without Kurds demarcation line for the North, Central and East of Asia. This will be opposited by Eastern Mediterranean -Arabian axis in Southwest Asia. Countries positioned to make real money out of this are Poland and Belarus. The Baltic ports will also prosper.
So, another die is cast.
Looks like the World will return to a bipolar structure. The multipolar World as envisioned in the 1990s hasn't worked out.
