A word from the Shaykh about the Qur'an and that it is a cure for diseases through its contemplation.

The Shaykh : Praise be to Allah, Lord of the worlds, and I send prayers and peace upon our Prophet Muhammad, the Seal of the Prophets, the Imam of the righteous, and the leader of the white-ankled ones, and upon his family and his Companions, and those who follow them with excellence until the Day of Judgment.
As for what follows, this is the thirty-first meeting, as our brother, Shaykh Mahmud ibn 'Abd al-'Aziz al-Sa'igh, the manager of the Da'wah office in Unaizah, stated. It is the monthly meeting that takes place on the night of the third Sunday of every month, and this night is the night of the nineteenth Sunday of the month of Jumada al-Thani, 1416 AH.
On this night, we speak about the interpretation of the Noble Qur'an, for Allah, Mighty and Majestic, revealed this Qur'an to the people so that they may recite it, and so that they may attain blessing through its recitation. Whoever reads a letter from it has ten good deeds for him. So if a person says: then in every letter of it are ten good deeds, because every letter of it is a good deed, and a good deed is multiplied by ten. Allah the Exalted revealed it as a cure for what is in the breasts, and the breasts are the location of the hearts. For this reason, He said: and what is in the breasts are the hearts, as the Exalted said: The hearts may have a disease, and rust may be upon them, and they may have a disease either from the dominance of desire, meaning: from the dominance of a will that inclines the person away from the truth. He becomes preoccupied with the world over religion, preoccupied with the love of authority, the love of fame, the love of honor, the love of being revered and honored, instead of humility and submission to the Lord of the worlds. We seek refuge in Allah from that. The hearts have a disease of doubt, where the truth becomes confused for the person so that he does not distinguish between the truth and falsehood. Rather, he may see falsehood as truth and truth as falsehood, and thus he perishes. The hearts have rust upon them, and their rust is sins. And when sins accumulate upon the hearts, they block the paths of good from them. Allah, Blessed and Exalted is He, said: Nay, meaning: it is not like the tales of the ancients rust accumulated upon them and gathered upon them what they used to earn of evil deeds, until they saw the greatest speech they had ever seen as the tales of the ancients. So know that whenever you are prevented from understanding the speech of Allah, that is only due to sins that have accumulated upon your heart. Otherwise, if your heart were pure and clear, you would see that the speech of Allah the Exalted is the greatest speech, the truest speech, the best speech, and the most excellent speech. The Qur'an is a cure for bodies, even bodies; the Qur'an is a cure for them. Let us leave aside the diseases of the hearts; the diseases of the hearts are hidden diseases that are treated by this great revelation. But even physical diseases are treated by this great revelation. Even physical diseases are treated! A group of people descended upon a people whom the Prophet (peace and blessings be upon him) had sent on a raid, but those upon whom they descended did not host them. So the Companions moved aside to one side. Then Allah sent a scorpion with a severe sting, and it stung their master, so he was afflicted by it. They sought a healer to heal him, and they said: Perhaps with these people there is a healer. So they came to the Companions and said: Your master has been stung, do you have a healer? They said: Yes, we have someone who can recite ruqyah, but do you have a reward, meaning compensation? They said: Yes, for you is this flock of sheep, save our companion. So one of the people went and began to recite over this stung person with the Opening of the Book. What is the Opening of the Book? He recited it over him, and he rose up as if he had been untied from a rope, meaning: as if he were a camel whose rope had been untied. He sprang up energetic due to the recitation of the Fatihah over him. So they took the flock until they reached the Messenger of Allah (peace and blessings be upon him) and asked him about it. He said: He said this, may the prayers and peace of Allah be upon him, to reassure their hearts and to remove what was in their hearts of doubt. Then he said to the one who recited it: This is a tested matter, but it does not benefit except one who believes in it, both the reciter and the one over whom it is recited. If the reciter is a believer and the one over whom it is recited is a believer in the benefit of this Qur'an, the patient benefits from it. But if he recites it by way of doubt and experimentation, it does not benefit. The Qur'an is a cure even for physical diseases, as in this example. And it has been tested that it is written on al-haza. Do you know al-haza? Yes, sores and boils that appear on the foot or the hand or the forearm. It is written on them If this verse is written on them once or twice, it disappears by the permission of Allah; it disappears completely. If you placed on them all the known medicines, they would not benefit. But write this verse on them, and they will dry up and disappear. This is a tested matter. In difficult childbirth, when childbirth becomes difficult for a woman sometimes, read in water, or write with saffron on the walls of the vessel the verses in which Allah, Glorified and Exalted is He, is concerned with the pregnancy, such as: and such as: and such as: and similar verses. Then the woman whose childbirth is difficult drinks it and wipes around the area, and by the permission of Allah, the delivery of the fetus will be made easy. But as I said, the matter requires what? It requires faith from whom? From the reciter and the one over whom it is recited. So the result is that the entire Qur'an is good. But was the Qur'an revealed for this only? No. Contemplating the verses means: reflecting on their meaning, and seeking to know them. meaning: he takes a lesson. So Allah, Mighty and Majestic, began first with knowing the meaning, then with action, because action without knowing the meaning is not possible, and perhaps the action will corrupt more than it fixes.
