Hisham bin Urwah narrates from his father that when Sayyiduna Abdullah bin al-Zubayr (may Allah be pleased with them both) was martyred, he said: I heard Abdullah bin al-Zubayr saying: "Whoever denies trials, let him do so; I do not deny them. It has reached me that Sayyiduna Yahya bin Zakariyya (peace be upon him) was killed on account of an adulterous woman who was a slave girl." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), and some of the Egyptians have narrated it from Yahya bin Ayyub as a musnad (connected) report.
