W-Salam Dr Saheb,
He has done his courses under Dr Israr Ahmed (RA)'s Tanzeem-e-Islami (Faisalabad branch) and for forty years Dr Saheb (RA)'s placed Shaykhul-Hind's Tafseer in front of him and did lectures and so does everybody from Tanzeem, heavily based on works of Ulamah of Deoband.
Deobandees abandoned the location (Masjid) of Tafseer of Maulana Ahmed Ali Lahori (RA) and Dr Israr Ahmed Saheb (RA) started his Dars from that very location.
For decades on TV Dr Israr Ahmed (RA) debated with Barelwees, Modernists, Atheists, Secualrists and routed them and it was for the whole nation to see, Deobandees did nothing like this (forget TV but not even on Radio or conferences).
After serving the Deen for 40+ years the Ulamah of Deoband COULD NOT FIND:
So they fell back on the age old excuse that he wasn't an Alim.
They are NOT Ulamah (as in graduates of Darul-uloom) and that is correct but the issue is WHY are ULAMAH so disconnected from youth and mainstream that people are turning to them.
Second issue which is most pressing for Deobandees is to critically analyse this thread by London786, there are people on this who are refuting Aqeedah who are NOT ULAMAH and if by having Ijazahas these people on this pdf have become Ulamah then Dr Israr Ahmed (RA) and NAK are both also Ulamah because they also have Ijazahs.
So which way should the Deobandees plead? Labelling people Ulamah when it suits them and then taking the label off when it doesn't?
Yes here is the Fatwa by Askimam.org
Here is son of Dr Israr Ahmed (RA) outlining his views on Shaykhul-Hind (RA) addressing a gatehring of Deobandi Ulamah and laymen:

This cannot be undone and I am sure it will be greatly appreciated.
