You should know that the duty to the Book of Allah (The Qur’an) entails practicing on its injunctions, be they commands or prohibitions, fearing its warnings, having hope in its promises, believing in its allegorical verses and taking admonition from its parables.
If you do this, you would have come out of the pitch darkness of ignorance towards the light of knowledge, and from the torment of doubts to the comfort of conviction
Allah jalllajalaaluhu says;
ٱللَّهُ وَلِىُّ ٱلَّذِينَ ءَامَنُوا۟ يُخْرِجُهُم مِّنَ ٱلظُّلُمَٰتِ إِلَى ٱلنُّورِ
Allah is the helper of the Believers, He removes them from the pit of darkness towards light
From “The Sunnah way of the Sufis”
