It is practically impossible to get someone convicted for adultery in Islam for a variety of reasons; but there is no disagreement about stoning (rajm) as the punishment for adultery. The Prophet ﷺ upon him peace, pronounced and carried out rajm upon three married Muslims - one man and two women - and two Jews, a man and a woman.
Stoning for adultery is mass-transmitted from the Prophet ﷺ upon him peace, both as verbal injunction (Hadith "The child belongs to the household where he is born and the adulterer gets stones") and actual deed (stoning of Maa`iz ibn Maalik, Allah be well-pleased with him) cf. al-Kattani, Nazm al-Mutanathir (p. 105-106 §181-182). Furthermore, there is complete consensus in the first three generations of Islam - both in law and in its application by the Four Caliphs - that the hadd of adultery for the married is stoning, cf. Ibn Qudama, al-Mughni (8:158); Ibn Hajar, Fath al-Bari (12:118). i.e. some say there are no stoning verses on the Qur'an, whilst as far as I know, unmarried individuals get lashes and banishment, whilst married people get lashes and stoning.
There are three types of abrogated Qur'anic verses:
(1) recitation-abrogated and ruling-abrogated
(2) recitation-established and ruling-abrogated
(3) recitation-abrogated and ruling-established
The verses that concern stoning as the punishment for a married person's adultery are of type (3) cf. al-Suyuti, al-Itqan fi `Ulum al-Qur'an (Type 47 of the Qur'anic Sciences, 2:718 of the Mustafa al-Bugha 1993 2nd edition, Dar Ibn Kathir).
[Note: in the case of "forcible adultery" (zina bil-jabr) i.e. rape - then the offender also faces death or (short of enough proof) long-term imprisonment regardless of marital status.]

This is not entirely correct, as clarified already. (See separate post about the website quoted above.) And Allah knows best.
