on the authority of Abū Hurayrah (may Allah be pleased with him):
The Prophet ﷺ said, “Woe to the Arabs for an evil that has drawn near! Tribulations will come like patches of a pitch-black night: in the morning a man will be a believer and by evening a disbeliever; he will barter away his religion for a trifling portion of this worldly life. Whoever among them holds fast to his faith will be like one who clutches a thorny branch, or a burning coal of al-ghaḍā.(1)

Abū Yūnus here is Sulaym ibn Jubayr, one of Abū Hurayrah’s freedmen, and he is trustworthy. This is the highest-grade chain we possess for a hadith from Abū Hurayrah.

Aḥmad ibn Salām and al-Khaḍir ibn Ḥammūyah—by authorization—narrated to us from Abū al-Faraj ibn Kulayb; he informed us, saying: Ibn Bayān informed us, Muḥammad ibn Makhlad informed us, Ismāʿīl al-Ṣaffār narrated to us, al-Ḥasan ibn ʿArafah narrated to us, ʿAmmār ibn Muḥammad narrated from al-Ṣalt ibn Quwayd al-Ḥanafī: I heard Abū Hurayrah say:
“The Messenger of Allah ﷺ said, ‘The Hour will not be established until the horned animal no longer gores the hornless one.’(2)”

Al-Ṣalt—whom al-Nasāʾī gave the kunya Abū al-Aḥmar—was then described by him: “I do not know what to make of him.” He subsequently cited this very hadith and added: Aḥmad ibn ʿAlī—meaning al-Marwazī—said, “ʿAbd Allāh ibn ʿAwn al-Kharrāz narrated to us, from ʿAmmār.”
