Sheikh Muhammad Muhammad Sâlim `Abd al-Wadûd
The Qur’ân can be read upon non-Muslims for the purpose of healing. This is established in the Sunnah.
Abû Sa`îd al-Khudri relates the following [Sahîh al-Bukhârî (5295)]:
Some of the Prophet’s Companions came to an Arab settlement, but the inhabitants did not allow them to water their animals.
Then it happened that their chieftain was stung by a scorpion and asked: “Does anyone among you have medicine or the ability to perform ruqyah?”
The Companions replied: “You did not give us leave to water our animals. We will not do anything unless you pay us.”
They agreed to pay the Companions a number of sheep. Then one of the Companions began to recite Sûrah al-Fâtihah, gathering the moisture of his breath together and blowing it on the wound.
The man’s wound was healed by this, so he brought the sheep to them. The Companions conferred among themselves: “We ill not take these as our own until we consult with the Prophet (peace be upon him).
When they went and asked him, he laughed, and said: “And how did you come to know that (Sûrah al-Fâtihah) is a ruqyah? Take the sheep, and let me share with you.”
This hadîth shows that reading the Qur’ân can provide healing for non-Muslims. It also shows the Prophet’s approval of doing so. It tells us the Sûrah al-Fâtihah is a particularly good chapter for ruqyah.
This is not contradicted by the verse: “And We send down in the Qur’ân that which is a healing and a mercy to those who believe, and it increases the wrongdoers in nothing but loss.” [Sûrah al-Isrâ’: 17:82]
The believers benefit from both the healing and the mercy of these verses. That benefit extends to their physical as well as spiritual lives and it applies to Allah’s mercy upon them in this world and the Hereafter.
This does not contradict the idea that the Qur’ân can be a healing for the physical ailments of those who reject its message, while not otherwise being a mercy for them in either this world or the next.
As for the Qur’ân increasing them in nothing but loss, we can understand to apply to the consequences in the Hereafter for those who, after hearing the message of the Qur’ân and understanding it, choose to reject it and disbelieve in its message.
And Allah knows best.
