آخِرُ شِدَّةٍ يَلْقَاهَا الْمُؤْمِنُ الْمَوْتُ وَفِي قَوْلِهِ {يَوْمَ تَكُونُ السَّمَاءُ كَالْمُهْلِ} [المعارج 8] قَالَ كَدُرْدِيِّ الزَّيْتِ وَفِي قَوْلِهِ {آنَاءَ اللَّيْلِ} [آل عمران 113] قَالَ جَوْفُ اللَّيْلِ وَقَالَ هَلْ تَدْرُونَ مَا ذَهَابُ الْعِلْمِ؟ قَالَ هُوَ ذَهَابُ الْعُلَمَاءِ مِنَ الأَرْضِ
