About the importance of the Quran
Nahj al-Balāgha|Volume 1|Book 1|Chapter 183
أَقُولُ مَا تَسْمَعُونَ، وَاللهُ الْمُسْتَعَانُ عَلى نَفْسِي وَأَنْفُسِكُمْ، وَهُوَ حَسْبُنَا ﴿وَنِعْمَ الْوَكِيلُ﴾!
I say what you are hearing. I seek Allāh’s help for myself and yourselves. He is enough for me and He is an excellent trustee (3:173).
