All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
This narration is correct and it is reported by Al-Bukhari and Muslim. It is mentioned in Fatwa: 85019. The meaning of the narration is that stoning to death is confirmed by the Qur'an as it is confirmed by the Sunnah and the act of the companions . The verse in this narration is among those verses whose text were abrogated as the scholars stated, but its ruling remained valid.
For more benefit, it should be noted that texts that have been abrogated (whether from Qur'an or the Sunnah) are of two kinds:
1) Verses whose text and ruling has been abrogated (i.e. neither the text of the verse remained nor the ruling), like what 'Aa'ishah narrated that ''at the beginning ten known sucklings make the woman a Mahram for the baby who suckled from her, this was later abrogated.'' [Muslim]
2) Verses whose texts were abrogated but their ruling remained, like the verse of stoning to death (of adultery).
3) Verses whose texts remained by their rulings were abrogated, like the saying of Allaah (which means): {And those who are taken in death among you and leave wives behind - for their wives is a bequest: maintenance for one year without turning [them] out.}[Qur'an 2:240].
Allaah knows best.
