According to the Quranic verses what is the best reward for the true believers?

You mean for martyrs? It's 72 raisins.

Eternal paradise.

Garden of Eden

Well, first of all, you can NEVER be sure in islam if you are one of the true believers.

So it is best not to get your hopes up by thinking about such things.

Alcohol that does not get you drunk and women who never learn how to pleasure you as they are perpetually ignorant of sex. Oh and lots of milk and honey.

I think I prefer a vintner, cook and woman who know what they are doing.

Do you mean the reward in paradise or something else. Here are some verses, etc and on how's is it going to be like in Paradise. Surah: 16. an-Nahl

31. Gardens of Eternity which they will enter: beneath them flow (pleasant) rivers: they will have therein all that they wish: thus does Allah reward the righteous Surah: 18. al-Kahf 31. For them will be Gardens of Eternity; beneath them rivers will flow; they will be adorned therein with bracelets of gold and they will wear green garments of fine silk and heavy brocade; they will recline therein on raised thrones. How good the recompense! How beautiful a couch to recline on! Ibn Abbas (May Allah be pleased with him) said: “The roots of date palms in Paradise are of green emeralds. And their branches are red gold. And their leaves are clothing for the people of Paradise... Its fruits... are whiter than milk and purer than honey...” (Related by Abu Bakr ibn Abee Ad-Dunyaa) Also there are ranks in paradise of course the lowest rank a person earns in Paradise will be 10 times better than this world so imagine the best thing to do or something that is popular by the millions or billions of people in this world and times it by that.

Rivers of honey & milk or something like that...Oh! and wine that you can drink all day and not get drunk.

I hate milk lactose intolerant and wine is only good occasionally.
