The Messenger of Allah ﷺ said, "Among the signs of the Hour are that wealth will become abundant and widespread, trade will flourish, knowledge will become widely available, and a man will be offered a sale and will say, 'No, not until I consult the merchant of such-and-such tribe.' And a scribe will be sought in a large neighborhood but none will be found."
قال رسول الله ﷺ: إن من أشراط الساعة أن يفشو المال ويكثر، وتفشو التجارة، ويظهر العلم، ويبيع الرجل البيع، فيقول: لا حتى أستأمر تاجر بني فلان، ويلتمس في الحي العظيم الكاتب فلا يوجد.
Nasai (4456), Hakim (72), and Khattabi in Gharib al-Hadith (1/405) all narrated it, all through the hadith of Wahb bin Jareer, who said, "My father told me, from Yunus, from Hasan, from Amr bin Taghlib," and he related it. The wording given is that of Nasai. Hakim restricted himself to his statement, "and trade will spread." As for Khattabi, he made the statement "and a man sells the sale" and what follows it part of the speech of Amr bin Taghlib. Its chain is sahih.Hakim said, "This is a hadith sahih in its chain, though the two of them [Bukhari and Muslim] did not include it. Its chain meets their standard and is sahih, except that Amr bin Taghlib has no narrator other than Hasan."However, Ibn Abu Hatim said in Al-Jarh wal-Tadil (3/222), in the entry on Amr bin Taghlib, "He was a companion. Hasan Basri and Hakam bin Aaraj narrated from him."An explicit statement of direct narration has come in the hadith about fighting the Turks in Sahih Bukhari (2927) and Musnad Ahmad (20674), and that too is among the signs of the Hour. It appears, then, that Amr bin Taghlib narrated two hadiths about the signs of the Hour that Hasan heard from him, and some narrators altered the wording of transmission.Hasan also has other hadiths in Musnad Ahmad from Amr bin Taghlib in which he explicitly stated direct narration from him.
