The Prophet ﷺ used to say, "Woe to the Arabs from an evil that has drawn near. Trials like patches of dark night, in which a man wakes up a believer and goes to sleep an unbeliever, and goes to sleep a believer and wakes up an unbeliever, selling his religion for a small worldly gain. The one among them holding fast to his religion on that day will be like one grasping thorny branches or burning embers of ghada wood."
أن النبي ﷺ كان يقول: ويل للعرب، من شر قد اقترب فتن كقطع الليل المظلم يصبح الرجل فيها مؤمنا ويمسي كافرا، ويمسي مؤمنا ويصبح كافرا، يبيع دينه بعرض من الدنيا قليل، المتمسك منهم يومئذ على دينه كالقابض على خبط الشوك أو جمر الغضى.
Ahmad (9073) narrated it from Yahya bin Ishaq and Hasan (that is, Ibn Musa), and Jafar Firyabi in Sifat al-Munafiq (100) narrated it from Qutayba bin Saeed, both of them from Ibn Lahia, from Abu Yunus (that is, Salim bin Jubayr, the freed slave of Abu Hurairah), from Abu Hurairah, and he related it. The wording is that of Firyabi. Its isnad is hasan, for although Ibn Lahia was weak in memory, some scholars accepted what Qutayba narrated from him.As for his statement, "Tribulations like pieces of the dark night... he sells his religion for a trifle of this world," Muslim narrated it in the Book of Faith (118) through the route of Ala bin Abdul-Rahman, from his father, from Abu Hurairah, and it is mentioned in its proper place.
