Among the signs of the nearness of the Hour is that the wicked are raised and the good are lowered

It is narrated from Amr bin Qays al-Kindi that he said: I was with my father at Huwwarin, and I was still a young boy. I saw that people had gathered around a man, so I asked: Who is this? The people said: This is Abdullah bin Amr bin al-As (may Allah be pleased with them both). I heard him narrating this hadith of the Messenger of Allah (peace and blessings be upon him), that he (peace and blessings be upon him) said: "Among the signs of the Hour is that the wicked will be raised up and the good will be brought low, much talk will be made and deeds will be stored away (or deeds will disappear), and the 'Mathnah' will be read among the people, and there will not be a single person among them who objects to it (and forbids it)." It was asked: What is the 'Mathnah'? He said: "Whatever (laws or books) are written other than the Book of Allah, the Mighty and Majestic (and people begin to give them preference over the Qur'an)."

It is narrated from Amr bin Qays al-Sakuni that he said: I went with my father in a delegation to Sayyiduna Mu'awiyah (may Allah be pleased with him), and I heard a man narrating this hadith to the people: "Among the signs of the Hour is that the wicked will be raised up and the good will be brought low, action and deeds will be stored away (or deeds will disappear) and talk will prevail (rhetoric will increase), and the 'Mathnah' will be read among the people, and there will be no one among them who changes it or objects to it (and forbids it)." It was asked: What is the 'Mathnah'? He said: "Whatever (writings) are written other than the Book of Allah." Amr bin Qays said: I narrated this hadith to some people among whom was Isma'il bin Ubaydullah, and he said: I too was with you in that gathering. Do you know who that (narrating) man was? I said: No. He said: He was (the Companion of the Messenger) Sayyiduna Abdullah bin Amr (may Allah be pleased with them both).
This hadith is sahih (authentic) through both chains, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Abu Qabil al-Ma'afiri that he said: We were with Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) when he was asked which of the two cities (of the Romans) would be conquered first: Constantinople or Rumiyah (Rome)? He called for an old chest, took a book out of it, looked into it and said: We used to sit with the Messenger of Allah (peace and blessings be upon him) writing down everything he (peace and blessings be upon him) said (even the details of yes and no). He (peace and blessings be upon him) was asked which city would be conquered first: Constantinople or Rumiyah? The Messenger of Allah (peace and blessings be upon him) said: "The city of Heraclius will be conquered first", meaning Constantinople.
This hadith has a sahih (authentic) chain, but the two Shaykhs (Bukhari and Muslim) did not record it.
