Where in the Koran is fortune-telling forbidden?

Sorry, I think it's only a hadith:

The Prophet (salAllahu alayhi wasalam) said: "The prayer of one who approaches a fortune-teller and asks him about anything, will not be accepted for forty days or nights" and: "Whosoever approaches a fortune-teller and believes in what he says, has disbelieved in what was revealed to Muhammed"

And actually a surah:

'Shall I inform you (O people!) Upon whom the devils) descend' They

descend on every lying, sinful person. Who lends an ear (to the devils and they

pour what they may have heard of the Unseen from the angels), and most of them

are liars.' (26:221-223)

Holy Quran 5:90

------------------

يَا أَيُّهَا الَّذِينَ آمَنُوا إِنَّمَا الْخَمْرُ وَالْمَيْسِرُ وَالْأَنصَابُ وَالْأَزْلَامُ رِجْسٌ مِّنْ عَمَلِ الشَّيْطَانِ فَاجْتَنِبُوهُ لَعَلَّكُمْ تُفْلِحُونَ

O you who have believed, indeed, intoxicants, gambling, [sacrificing on] stone alters [to other than Allah], and divining arrows are but defilement from the work of Satan, so avoid it that you may be successful.

"…If I knew the unseen, I could have acquired much wealth, and no harm would have touched me. I am not except a warner and a bringer of glad tidings to a people who believe." [Quran 7:188]

"And with Him [i.e., Allaah] are the keys of the unseen; none knows them except Him." [Quran 6:59] As well as (what means): "Say (O Muhammad): 'None in the heavens and earth knows the unseen except Allaah…'" [Quran: 27:65]

and it's spelled Qur'an
