وَإِنَّمَا سُمِّيَتِ الشُّبْهَةُ شُبْهَةً لاِنَّهَا تُشْبِهُ الْحَقَّ، فَأَمَّا أَوْلِيَاءُ اللهِ فَضِيَاؤُهُمْ فِيهَا الْيَقِينُ، وَدَلِيلُهُمْ سَمْتُ الْهُدَى وَأَمَّا أَعْدَاءُ اللهِ فَدُعَاؤُهُمْ الضَّلالُ، وَدَلِيلُهُمُ الْعَمْى، فَمَا يَنْجُو مِنَ المَوْتِ مَنْ خَافَهُ، وَلا يُعْطَى الْبَقَاءَ مَنْ أَحَبَّهُ.
Doubt is named doubt because it resembles truth. As for lovers of Allāh, their conviction serves them as light and the direction of the right path (itself) serves as their guide; while the enemies of Allāh, in time of doubt call to misguidance in the darkness of doubt and their guide is blindness (of intelligence). One who fears death cannot escape it nor can one who fears for eternal life secure it.
