So if you are in a doubt regarding that which We have sent down to you then ask those who read the book (which was revealed) before you. The truth has indeed come to you from your Fosterer so do not be of those who doubt.
The coming of Prophet Muhammed (PBH) was mentioned in Torah and Injeel. This can be confirmed by referring to the original books. Even after this confirmation if one rejects the Quran then he will face the consequences of the earlier infidels.

Then why was there not a single city which believed so that their belief would have profited them, except the people of Yunus? When they believed We removed from them the punishment of disgrace from the life of this world and We gave them provision till a time.
It is reported that the community to which Yunus (PBH) was sent believed on seeing the punishment, Their belief was a service of profit to them in this world.

And had your Fosterer willed, those who are in the earth would have believed, all of them together. Will you then compel mankind till they become believers?
People believe only when Allah (SWT) makes them to believe. No one can be made to believe by compulsion. If Allah (SWT) had willed He could have made everyone to believe but He has not done so.
