Note: The majority of scholars interpret this to mean that these things in and of themselves do not transmit or cause harm through supernatural or hidden means but that Allah is ultimately in control and any fearful superstition around these is false.

We said, "He dislikes the medicine as a patient usually does." But when he came to his senses he said, "Did I not forbid you to put medicine (by force) in the side of my mouth?"

It is used as a snuff for treating throat and tonsil disease and it is inserted into one side of the mouth of one suffering from pleurisy."

Narrated `Aisha: (the wife of the Prophet) When the health of Allah's Messenger (ﷺ) deteriorated and his condition became serious, he asked the permission of all his wives to allow him to be treated In my house, and they allowed him. He came out, supported by two men and his legs were dragging on the ground between `Abbas and another man. (The sub-narrator told Ibn `Abbas who said: Do you know who was the other man whom `Aisha did not mention? The sub-narrator said: No. Ibn `Abbas said: It was `Ali.) `Aisha added: When the Prophet entered my house and his disease became aggravated, he said, "Pour on me seven water skins full of water (the tying ribbons of which had not been untied) so that I may give some advice to the people."

Then he went out to the people and led them in prayer and delivered a speech before them.

We are owners of livestock and have never been farmers," and they found the climate of Medina unsuitable for them. So Allah's Messenger (ﷺ) ordered that they be given some camels and a shepherd, and ordered them to go out with those camels and drink their milk and urine. So they set out, but when they reached a place called Al-Harra, they reverted to disbelief after their conversion to Islam, killed the shepherd and drove away the camels. When this news reached the Prophet (ﷺ) he sent in their pursuit (and they were caught and brought). The Prophet (ﷺ) ordered that their eyes be branded with heated iron bars and their hands be cut off, and they were left at Al-Harra till they died in that state.

So `Umar called them, consulted them and informed them that an epidemic had broken out in Sham. Those people differed in their opinions. Some of them said, "We have come out for a purpose and we do not think that it is proper to give it up," while others said (to `Umar), "You have along with you. other people and the companions of Allah's Messenger (ﷺ) so do not advise that we take them to this epidemic." `Umar said to them, "Leave me now." Then he said, "Call the Ansar for me." I called them and he consulted them and they followed the way of the emigrants and differed as they did. He then said to them, Leave me now," and added, "Call for me the old people of Quraish who emigrated in the year of the Conquest of Mecca." I called them and they gave a unanimous opinion saying, "We advise that you should return with the people and do not take them to that (place) of epidemic." So `Umar made an announcement, "I will ride back to Medina in the morning, so you should do the same." Abu 'Ubaida bin Al-Jarrah said (to `Umar), "Are you running away from what Allah had ordained?" `Umar said, "Would that someone else had said such a thing, O Abu 'Ubaida! Yes, we are running from what Allah had ordained to what Allah has ordained. Don't you agree that if you had camels that went down a valley having two places, one green and the other dry, you would graze them on the green one only if Allah had ordained that, and you would graze them on the dry one only if Allah had ordained that?" At that time `Abdur-Rahman bin `Auf, who had been absent because of some job, came and said, "I have some knowledge about this. I have heard Allah's Messenger (ﷺ) saying, 'If you hear about it (an outbreak of plague) in a land, do not go to it; but if plague breaks out in a country where you are staying, do not run away from it.' " `Umar thanked Allah and returned to Medina.

Narrated `Aisha: (the wife of the Prophet) that she asked Allah's Messenger (ﷺ) about plague, and Allah's Messenger (ﷺ) informed her saying, "Plague was a punishment which Allah used to send on whom He wished, but Allah made it a blessing for the believers. None (among the believers) remains patient in a land in which plague has broken out and considers that nothing will befall him except what Allah has ordained for him, but that Allah will grant him a reward similar to that of a martyr."

Narrated `Aisha: During the Prophet's fatal illness, he used to recite the Mu'auwidhat (Surat An-Nas and Surat Al- Falaq) and then blow his breath over his body. When his illness was aggravated, I used to recite those two Suras and blow my breath over him and make him rub his body with his own hand for its blessings." (Ma`mar asked Az-Zuhri: How did the Prophet (ﷺ) use to blow? Az-Zuhri said: He used to blow on his hands and then passed them over his face.)
