Musannaf Ibn Abi Shayba 19:819

Abu Bakr narrated to us, he said: Isa ibn Yunus narrated to us, from al-Awza’i, from al-Zuhri, who said: If a man accused a man of adultery (qadhf), then he pardoned him and called witnesses to it, then he brought him to the Imam after that, he would take his right for him. And even if he waited for thirty years.
