Musannaf Ibn Abi Shaybah 30743 — Testimony of zina: how is it given?

Abu Uthman said: When Sayyiduna Abu Bakrah (may Allah be pleased with him) and his two companions testified against Sayyiduna al-Mughirah (may Allah be pleased with him), Ziyad came. Sayyiduna Umar (may Allah be pleased with him) said to him: A man who will never testify, if Allah wills, except to the truth. He said: I saw panting and an evil sitting. At this Sayyiduna Umar asked: Did you see it like the kohl stick entering the kohl container? He said: No. So Sayyiduna Umar gave an order concerning them, and all of them were flogged.
