The Qur’an is the divine book revealed by Allah to guide mankind. While it helps increase the faith of the believers, it exposes the denial of the unbelievers. “He it is Who has sent down to thee the Book:
In it are verses basic or fundamental (of established meaning); they are the foundation of the Book: others are allegorical. But those in whose hearts is perversity follow the part thereof that is allegorical, seeking discord, and searching for its hidden meanings, but no one knows its hidden meanings except Allah. And those who are firmly grounded in knowledge say:
‘We believe in the Book; the whole of it is from our Lord’, and none will grasp the Message except men of understanding.”
That means that some verses of the Qur’an have the capacity both to reveal the transgressions of “those whose hearts are flawed by perversity” and to increase the faith and submission of the believers. It should be noted, however, that no one can guarantee that he will continue to preserve his faith. Believers may also lose the Qur’anic point of view with the effect of Satan’s temptations. Naturally they would not perceive the wisdom in the Qur’an if they read it while under the sway of Satan. That is why Allah commands believers to seek refuge in Him from the evil influence of Satan before reading the Qur’an:
“When you read the Qur’an, seek Allah’s protection from Satan, the rejected one.”
This command of Allah is important for it reminds believers of Satan's constant presence and unceasing activities. Indeed, Satan is ever at work, lying in wait for people on Allah’s straight path, and trying to assault them “from before and behind, from their right and from their left.” The strategies of Satan have been explained in many verses of the Qur'an. Thus salvation from the deceits of Satan can be achieved only through the Qur’an, which warns us against Satan’s tricks and tells us to avoid them. As expressed in the 42 nd verse of Surat al-Hijr, “Satan has no authority over Allah's servants.” The solution is to accept the Qur’an as the only guide and to read it after seeking refuge in Allah from the rejected Satan.
