The conversation of Asma (may Allah be pleased with her) with al-Hajjaj after Ibn al-Zubayr (may Allah be pleased with him)

It is narrated from Abu al-Siddiq that he said: When al-Hajjaj (bin Yusuf) overcame Sayyiduna Ibn al-Zubayr (may Allah be pleased with them both), martyred him and desecrated his body, he went to the mother of Sayyiduna Abdullah, Sayyidah Asma' bint Abi Bakr (may Allah be pleased with them both). She said: "How do you ask permission to see me when you have killed my son?!" Al-Hajjaj said: "Your son deviated in the Sanctuary of Allah, so I killed him as a disobedient heretic, until Allah made him taste a painful punishment," and he said a great deal about him. She said: "You have lied, O enemy of Allah and enemy of the Muslims! By Allah, you killed him while he was one who fasted much, stood in prayer at night, was dutiful to his parents and was a guardian of this religion. If you have ruined his world, he has ruined your Hereafter. And indeed the Messenger of Allah (peace and blessings be upon him) narrated this hadith to us: 'Two great liars (kadhdhab) will emerge from the tribe of Thaqif; the second of them will be worse than the first, and he will be the destroyer (mubir, extremely bloodthirsty and ruinous).' And O Hajjaj, that is none other than you."

It is narrated from Husayn that he mentioned a similar hadith and added in it: Then al-Hajjaj said: "The Messenger of Allah (peace and blessings be upon him) spoke the truth and you have spoken the truth. I am the 'mubir' (the destroyer); I destroy the hypocrites."
This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Qays bin Ubad that he said: I used to come to Madinah to meet the Companions of the Messenger of Allah (peace and blessings be upon him), and of all of them, the one I most loved to meet was Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him). He says: I came to Madinah in the time of Sayyiduna Umar (may Allah be pleased with him). The iqamah was called for the Fajr prayer, and Sayyiduna Umar (may Allah be pleased with him) came out, and some other men were with him. A man from among the people began looking at the faces of the people; he recognised them but did not recognise me, so he pushed me (back from the row) and stood in my place. I prayed, but (because of the push) I was not aware of my prayer. When they had finished praying, he said: O my son! May Allah not cause you harm. I did not do what I did out of ignorance; rather, the Messenger of Allah (peace and blessings be upon him) instructed us: "Be in the row that is next to me" (those of you who are people of understanding and wisdom), and I looked at the faces of the people and recognised all of them except you. Then he sat down, and I have never seen people's necks strain towards anything as much as they strained towards him (out of reverence). It turned out that he was Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him). Among the things he said was: "By the Lord of the Ka'bah! The people of covenants (those in authority) are ruined. By the Lord of the Ka'bah! The people of covenants are ruined. By Allah, I do not grieve for them; I only grieve for the Muslims whom they have ruined."
This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "The destruction of my Ummah will be at the hands of some young boys (immature youths) of Quraysh."
This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it because of a disagreement between Imam Shu'bah and Sufyan al-Thawri (in its chain).

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that he said: I heard Abu al-Qasim (peace and blessings be upon him) say: "The corruption of my Ummah will be at the hands of some foolish young boys of Quraysh."
Amr bin Ali says that the correct name (of the narrator) is Malik bin Zalim.

It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that he said (about Gog and Magog): "Gog and Magog (Ya'juj and Ma'juj) are one span, two spans and three spans (in height), and they are from the descendants of Adam."
