Many Islamic Countries practices death punishment for Adultery. Although it is a major sin in Islam but I found no verse in Quran and hadeeth which says punishment of adultery is death.
References of Audeltry in Quran:
“Nor come nigh to adultery: for it is a shameful (deed) and an evil, opening the road (to other evils).”
— Qur'an, Sura 17 (Al-Isra), ayat 32
Surat an-Nur (the Light). The sura starts by giving very specific rules about punishment for zina:
"The woman and the man guilty of adultery or fornication,- flog each of them with a hundred stripes: Let not compassion move you in their case, in a matter prescribed by Allah, if ye believe in Allah and the Last Day: and let a party of the Believers witness their punishment."
— Qur'an, Sura 24 (An-Nur), ayat 2
It then turns to false accusations from members of the Muslim community to chaste righteous women:
“And those who accuse free women then do not bring four witnesses, flog them, (giving) eighty stripes, and do not admit any evidence from them ever; and these it is that are the transgressors.Except those who repent after this and act aright, for surely Allah is Forgiving, Merciful. ”
— Qur'an, Sura 24 (An-Nur), ayat 4-5
In Hadith, only these references are found and from what I understand it was for jews. look below:
Nearly all hadith collections include three hadiths that are central in the legal arguments about the punishment for zina:
One to the effect that the Prophet has enforced this punishment in a case of unlawful intercourse among Jews on the basis of the Torah;
a second one, transmitted by Abu Hurairah states that the Prophet, in a case of intercourse between a young man and a married woman, sentenced the woman to stoning and the young man to flogging and banishment for a year;
and a third one in which Umar al-Khattab asserts that there was a revelation to the effect that those who are muhsan (i.e. an adult, free, Muslim who has previously enjoyed legitimate sexual relations in matrimony regardless of whether the marriage still exists) and have unlawful intercourse are to be punished with stoning.
The hadith related by Abu Hurairah has been the basis of the fiqh doctrine.
The most accepted collection of Hadith Sahih al Bukhari has 4 entries (under 3829, 8804, 8805 and 8824) which refer to death by stoning. One case involved Jews who were stoned to death in accordance with the Law of the Torah (not the Qur'an). Another says: "A married man from the tribe of Bani Aslam who had committed illegal sexual intercourse and bore witnesses four times against himself was ordered by Mohammed to be stoned to death". These two hadiths clearly conflict as to who or what actually ordered the stoning. And in both entries, the narrator acknowledges his ignorance of whether the stoning to death was carried out before or after the revelation of Quranic Verse 24-2.
Even if there is hadith. how can it contradict Quran . Allah knows best
If anyone can advice it will be grateful because I am very confused for so many months about what I see in Quran and what I see how it has been implemented in Saudia Arabia, Iran and Afghanistan and other Islamic Counntries.
