The Prophet Muhammad:
بَادِرُوا بِالأعْمَال فتناً كقطَعِ اللَّيْلِ المُظْلِمِ ، يُصْبحُ الرَّجُلُ مُؤْمِناً وَيُمْسِي كَافِراً ، وَيُمْسِي مُؤمِناً ويُصبحُ كَافِراً ، يَبيعُ دِينَهُ بعَرَضٍ مِنَ الدُّنيا
You should rush towards virtuous deeds before you are overtaken by turbulent times like a portion of a pitch-dark night, times in which a person may wake up believing and lose faith by nightfall, or believe at nightfall and lose faith by morning, selling one’s religion for a paltry, worldly profit.
[Related by Muslim, al-Tirmidhi, Ahmad ibn Hanbal and Ibn Hibban on the authority of Abu Hurayrah]
A timely prescription, a warning and a truthful prediction. These insightful Prophetic words could not come at a more opportune time. The prescription is for general virtue, the prophecy a time of unprecedented turmoil of faith and intense greed.
