Hastening to do Good Deeds
فالأول: عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّه عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ قَالَ: بَادِرُوا بِالأَعْمَالِ فِتَنًا كَقِطَعِ اللَّيْلِ الْمُظْلِمِ يُصْبِحُ الرَّجُلُ مُؤْمِنًا وَيُمْسِي كَافِرًا وَيُمْسِي مُؤْمِنًا وَيُصْبِحُ كَافِرًا، يَبِيعُ دِينَهُ بِعَرَضٍ مِنَ الدُّنْيَا ((رَوَاهُ مُسْلِم)).
Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) said, "Be prompt in doing good deeds (before you are overtaken) by turbulence which would be like a part of the dark night. A man would be a believer in the morning and turn to disbelief in the evening, or he would be a believer in the evening and turn disbeliever in the morning, and would sell his Faith for worldly goods." [Muslim].
