Dr Israr Ahmed Saheb believes in no such thing that humans came from Monkeys. In his English lecture "Two Forms of Knowledge" he clearly explains his views on Evolution.
Evolution clearly occurs and is a scientific FACT! BUT there is no evidence that humans came from monkeys etc and to believe in such things is Kuf'r.
Your second objection doesn't render a person Kaafir, even if we were to accpet the Fatwa at face value, at best its an error.
There are errors in Dr Israr Ahmed Saheb's views about Jihad but I am not sure if even that makes him a Kaafir...
The man has served the book of Allah (SWT) for over 40+ years which is much more then most Ulama and people (alike) can produce for their efforts. He has refuted deviants, Hadeeth rejectors and blown them away and saved public from heresy.
What the Deobandi Ulama are now trying to do on TV (i.e. asnwering objections about Islam) he has been doing since 1979!) from his own pocket.
Lets not exaggerate the issue, he is but a man and bound to have committed errors so lets address facts.
There is a Fatwa on Jamia Binoria site which also talks about Dr Israr Ahmed but as usual has no facts in it...We have been here with Dr Farhat Hashmi as well. One half of Ulama issue Fatwaas (with not much details), the other half of Ulama go there give talks and make dua for Allah (SWT) to establish these institutions all over Pakistan.
It doesn't make sense! If there is deviancy and the person is committing Kuf'r then Ulama should first agree amongst each other. If a person is deviant then how come others keep co-operating with him?
In the case of Dr Farhat Hashmi, its Maulana Tariq Jameel.
In the case of Dr Israr Ahmed, it is a long list of Deobandi Ulama who continue to participate and lecture from the platform of Qur'aan Academy, Lahore. Lots of lectures on Terrorism and current affairs (from local Ulama) from Dr Israr Ahmed's place in Lahore.
Latest is this interview of Dr Israr Ahmed on a Deobandi media outlet:
As you can see from the disclaimer that they invite poeple from Ahlus-Sunnah Wal Jamaat.
Here is Zaid Hamid on the same channel:
