It was narrated from Jabir from 'Abdur-Rahman bin Abza that Abu Bakr 4 said:
I was sitting with the Prophet (ﷺ) when Ma'iz bin Malik came and confessed (to adultery) in his presence once, and he sent him away. Then he came and admitted it in his presence a second time and he sent him away. Then he came and admitted it in his presence a third time and he sent him away. I said to him: If you confess a fourth time, he will stone you. Then he admitted it the fourth time, so he detained him and asked about him, and they said: We do not know anything but good about him. Then he ordered that he be stoned.
