Stoning is clearly mandated in the Old Testament by Mosaic Law for certain specific crimes, as defined in that ancient society. The books of the Old Testament are part of the sacred scriptures of Judaism, Christianity, and Islam.

When Jesus gave his teachings he supplanted the old "eye for an eye" philosophies of the Old Testament with his new doctrines of forgiveness and nonviolence...which very clearly would forbid stoning people.

Christians claim to follow Jesus' teachings. If they did, they would definitely not stone people, burn them at the stake, or do other horrible things to them, but some Christians have historically done many such horrible things.

Muslims revere Jesus as a true prophet of God and claim to believe in his teachings. If they did, they would definitely not stone people or do other horrible things to them, but some Muslims have historically done many such horrible things.

The Jews (as a religious community) never accepted Jesus as a true prophet of God and do not include the New Testament in their teachings. Therefore it appears to me that the Jews are the one group among those 3 great religions who could, if they so desired, stone people without clearly violating their own stated religious beliefs and the teachings they claim to follow!

Ironical, isn't it?

The fact is, a lot of people in this world think they are following the teachings of some religion or other, but all they are really following is what some local authority figure or their own selfish nature told them to do. They are hypocrites...or they are just plain ignorant...or they are both. Probably both, I'd say.
