The reality is while Jinnah accidentally made Iqbal's dream a reality he punished and hurt his core support group who today are suffering in India. Ayesha Jalal has covered this aspect nicely.
In short Jinnah gave Pakistan to people who neither intially wanted it or were in danger. However those who needed protecting [India Muslims] were left even weaker and in greater danger.
Ayesha Jalal is not the authority on Jinnah. There are many who don't agree with her.
