Fear of God, praise for Islam, Muhammad, and the Quran
Nahj al-Balāgha|Volume 1|Book 1|Chapter 198
فَاتَّقُوا اللهَ الَّذِي نَفَعَكُمْ بَمَوْعِظَتِهِ، وَوَعَظَكُمْ بِرِ سَالَتِهِ، وَامْتَنَّ عَلَيْكُمْ بِنِعْمَتِهِ، فَعَبِّدُوا أَنْفُسَكُمْ لِعِبَادَتِهِ، وَاخْرُجُوا إِلَيْهِ مِنْ حَقِّ طَاعَتِهِ.
So, fear Allāh Who benefits you with His good advice, preaches to you through His Messenger, and obliges you with His favours. Devote yourselves to His worship, and acquit yourselves of the obligation of obeying Him.
