“We bestow of the Qur’ān do from on high what serves as a healing and a blessing to true believers.” (Suura Al-Israa : Verse 82) There is certainly a cure and a blessing for those whose hearts are full of faith. Such hearts brighten up and become ready to receive what the Qur’ān imparts of grace, reassurance and security. There is in the Qur’ān a healing power that cures obsession, anxiety and hesitation. It establishes a bond between the believer’s heart and God. This bond imparts inner peace to the believer as he experiences a feeling of security in God’s protection. He is happy and satisfied with what he receives from God and contented with his lot in life. Anxiety, hesitation and obsession are all terrible to experience. As the Qur’ān dispels all these, it is indeed a blessing for true believers.
In the Qur’ān we have a cure from carnal desires, greed, envy and evil thoughts. All these cause sickness of the heart and mind, leading to debility and utter ruin. As the Qur’ān cures these, it is a tool of grace bestowed by God on those who truly believe in Him.
The Qur’ān also provides a cure from deviant thoughts and feelings. It protects the mind from going far astray, while allowing it complete freedom within its fruitful pursuits. It stops the mind from wasting its energy over what is devoid of use. It lays down for it a sound approach that ensures good and useful results. The same principle applies to the human body, ensuring that its resources are utilized for what is useful and fruitful, steering human beings away from the suppression of natural desires or indulgence without restraint. Thus it ensures a healthy body. In this again we see that the Qur’ān is a means of God’s grace that is bestowed on believers.
There is also in the Qur’ān a cure for social ailments that weaken the structure of society and destroy its peace and security. Under the social system established by the Qur’ān society enjoys perfect justice in peace and security. This is again a further aspect of grace bestowed through the Qur’ān.
However, the Qur’ān “only adds to the ruin of the evildoers.” (Suura Al-Israa Verse 82) They make no use of the cure it provides or the blessings it brings about. They look with dismay at the believers as they feel proud to be among the followers of the Qur’ān. In their stubborn arrogance, the evildoers persist with their corrupt and unjust methods. Yet in this life, they are defeated by the followers of the Qur’ān, which makes them losers. In the life to come, they suffer for their arrogant disbelief and tyranny, and thus they lose again. Hence the Qur’ān adds to their ruin.
When man is left to his own devices, without the cure and blessing of the Qur’ān, and without consistent restraint of his whims and desires, he moves between two extremes: when he enjoys good fortune, he is arrogant and ungrateful, and when he experiences hardship he is given to despair. “Yet when We bestow Our blessings on man, he turns his back and draws arrogantly aside, and when he is afflicted by evil he gives himself up to despair.”(Suura Al-Israa:Verse 83)
Blessings and good fortune lead to arrogance unless one remembers where they come from and give thanks to God who bestowed them. On the other hand, when someone is afflicted by difficulty and hardship, he is easily lost in despair unless he trusts to God and hopes to receive His grace. It is when one truly relies on God that one feels that hardship will give way to what is better. This makes it clear that faith ensures God’s grace in situations of ease and difficulty alike.
The sūrah then states that everyone and every camp acts according to the path it follows. The final verdict on methods and actions is left to God alone: “Say: Everyone acts according to his own disposition. Your Lord is fully aware as to who has chosen the best path.” (Verse 84) In this statement we have an implicit warning as to the results of approaches and deeds. Hence, everyone needs to heed the warnings and strive to follow the path of Divine guidance which is available to all.
