A prophet says: there is wine in Paradise..!

They allege: Prophet of Islam tells his followers that there is wine in the Paradise… How can an impure thing exist in a holy place like Paradise..?!

And they use what is written in Muslim Correct number 3736Ibn 'Umar reported Allah's Messenger (Allah’s peace and blessings be upon him) as saying:
He who drank (wine) in this world would be deprived of it in the Hereafter.
