"Rush to do good deeds. A Fitnah will occur that is like a portion of the dark night, morning will come upon a man as a believer, who will be a disbeliever in the evening, and evening will come upon a believer, who will be a disbeliever in the morning. One of them will sell his religion for goods of the world."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ بَادِرُوا بِالأَعْمَالِ فِتَنًا كَقِطَعِ اللَّيْلِ الْمُظْلِمِ يُصْبِحُ الرَّجُلُ مُؤْمِنًا وَيُمْسِي كَافِرًا وَيُمْسِي مُؤْمِنًا وَيُصْبِحُ كَافِرًا يَبِيعُ أَحَدُهُمْ دِينَهُ بِعَرَضٍ مِنَ الدُّنْيَا
