could some1 give me the exact number of the verse in the koran that...?

The stoning for adultery is not part of the Qu'ran but actually in the "Sunnah" which is the religious/ legal traditions set up by Muhammad. The Qu'ran has a verse covering punishment of "fornication" (100 lashes) and adultery is specifically prohibition elsewhere in the Qu'ran, but does not give that punishment for adultery.

The Qu'ran in Sura 24- Ayat 2 says "The woman and the man guilty of fornication --flog each of them with a hundred stripes."

According to a note for this verse, it says that "fornication" the word "Zina" -- means a man and woman not married to each other - - they may or may not be married to someone else. This note says "Although zina covers both fornication and adultery, in the opinion of Muslim jurists, the punishment laid down here applies only to un-married persons. As for married persons, their punishment, according to the Sunnah of the Prophet (peace be upon him) is stoning to death. "

The Noble Qur'an An-Nur 24:2-9

2. The woman and the man guilty of illegal sexual intercourse, flog each of them with a hundred stripes. Let not pity withhold you in their case, in a punishment prescribed by Allâh, if you believe in Allâh and the Last Day. And let a party of the believers witness their punishment. (This punishment is for unmarried persons guilty of the above crime but if married persons commit it, the punishment is to stone them to death, according to Allâh's Law).

You are not a Muslim, you are just a liar.

MUSLIM means people who SUBMIT TO THE WILL OF GOD.

If you want the answer, it is the BEST to ask your husband then, he knows what sort of punishment to give you.
