If the adulterer is married, then the hadith is stoning, from Abdullah bin Abbas radiyallaahu 'anhuma said, Umar bin al-Khatthab radiyallaahu' anhu said, "Allah has sent Muhammad by bringing the truth and bringing down the book to him, among what Allah Subahanhu waTa 'ala down to him is the stoning verse, we read it, memorize it and understand it, the Prophet sallallaahu' alaihi wasallam has stoned and we did it after him, I am worried as the time passes there is someone who says, 'We do not find stoning verses in the book of Allah Subhanahu waTa'ala. 'As a result they are lost for leaving a duty handed down by Allah Subhanahu waTa'ala
