[Machine] I heard the Messenger of Allah ﷺ saying: "Indeed, before the Hour there will be trials like pieces of dark smoke. The heart of a person will die from it, just as his body dies. In the morning, a person will be a believer, and in the evening, he will be a disbeliever. Similarly, a person will be a believer in the evening, and in the morning, he will be a disbeliever. People will sell their religion for a small worldly gain."
And that you should consider him dead while you are his brothers and his companions amongst those trials.
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «إِنَّ بَيْنَ يَدَيِ السَّاعَةِ فِتَنًا كَقِطَعِ الدُّخَانِ يَمُوتُ مِنْهَا قَلْبُ الرَّجُلِ كَمَا يَمُوتُ بَدَنُهُ يُصْبِحُ الرَّجُلُ فِيهَا مُؤْمِنًا وَيُمْسِي كَافِرًا وَيُمْسِي مُؤْمِنًا وَيُصْبِحُ كَافِرًا يَبِيعُ فِيهَا أَقْوَامٌ دِينَهُمْ بِعَرَضٍ مِنَ الدُّنْيَا قَلِيلٍ» وَأَنْ يَزِيدَ قَدْ مَاتَ وَأَنْتُمْ إِخْوَانُنَا وَأَشِقَّاؤُنَا وَمِنْهَا
