In Islam and the Quran, is there anything about a person's or a muslim's words having creative/magical/fatalistic power? Like if someone confesses something is going to happen then it will happen? I don't mean using words to encourage or discourage someone or to have an influential effect, but that words in themselves materialise. For example if you say, "I think I'm going to fail that exam" will your words happen? Is there anything in Islam that teaches that? How would you feel about saying something bad is going to happen to yourself?
We have many but please I am not here to compare the qualities between Jesus(A.S) and Muhammad:saws

because I've seen this argument used by missionaries). We treat them as equals when it comes to being a messenger and prophet of Allah,only we believe Muhammad:saws: was the
last of them and
seal of prophet hood.
The Traditions mentioned below are all from Sahih al-Bukhari, the most authentic collection of ahadith.
Splitting of the Moon
"The Hour has drawn near, and the moon has been cleft asunder" [Qur'an 54:1]
Volume 6, Book 60, Number 388:
Narrated Abdullah:
The moon was cleft asunder while we were in the company of the Prophet, and it became two parts. The Prophet said, Witness, witness (this miracle)."
Food Multiplication
Volume 4, Book 56, Number 780:
Narrated Jabir:
My father had died in debt. So I came to the Prophet and said, "My father (died) leaving unpaid debts, and I have nothing except the yield of his date palms; and their yield for many years will not cover his debts. So please come with me, so that the creditors may not misbehave with me." The Prophet went round one of the heaps of dates and invoked (Allah), and then did the same with another heap and sat on it and said, "Measure (for them)." He paid them their rights and what remained was as much as had been paid to them.
Water Multiplication
Volume 4, Book 56, Number 779:
Narrated 'Abdullah:
We used to consider miracles as Allah's Blessings, but you people consider them to be a warning. Once we were with Allah's Apostle on a journey, and we ran short of water. He said, "Bring the water remaining with you." The people brought a utensil containing a little water. He placed his hand in it and said, "Come to the blessed water, and the Blessing is from Allah." I saw the water flowing from among the fingers of Allah's Apostle , and no doubt, we heard the meal glorifying Allah, when it was being eaten (by him).
Volume 4, Book 56, Number 777:
Narrated Al-Bara:
We were one-thousand-and-four-hundred persons on the day of Al-Hudaibiya (Treaty), and (at) Al-Hudaibiya (there) was a well. We drew out its water not leaving even a single drop. The Prophet sat at the edge of the well and asked for some water with which he rinsed his mouth and then he threw it out into the well. We stayed for a short while and then drew water from the well and quenched our thirst, and even our riding animals drank water to their satisfaction.
Volume 1, Book 7, Number 340:
Narrated 'Imran:
Once we were traveling with the Prophet and we carried on traveling till the last part of the night and then we (halted at a place) and slept (deeply). There is nothing sweeter than sleep for a traveler in the last part of the night. So it was only the heat of the sun that made us to wake up and the first to wake up was so and so, then so and so and then so and so (the narrator 'Auf said that Abu Raja' had told him their names but he had forgotten them) and the fourth person to wake up was 'Umar bin Al-Khattab. And whenever the Prophet used to sleep, nobody would wake him up till he himself used to get up as we did not know what was happening (being revealed) to him in his sleep. So, 'Umar got up and saw the condition of the people, and he was a strict man, so he said, "Allahu Akbar" and raised his voice with
Takbir, and kept on saying it loudly till the Prophet got up because of it. When he got up, the people informed him about what had happened to them. He said, "There is no harm (or it will not be harmful). Depart!" So they departed from that place, and after covering some distance the Prophet stopped and asked for some water to perform the ablution. So he performed the ablution and the call for the prayer was pronounced and he led the people in prayer. After he finished from the prayer, he saw a man sitting aloof who had not prayed with the people. He asked, "O so and so! What has prevented you from praying with us?" He replied, "I am
junub and there is no water. " The Prophet said, "Perform
tayammum with (clean) earth and that is sufficient for you."
Then the Prophet proceeded on and the people complained to him of thirst. Thereupon he got down and called a person (the narrator 'Auf added that Abu Raja' had named him but he had forgotten) and 'Ali, and ordered them to go and bring water. So they went in search of water and met a woman who was sitting on her camel between two bags of water. They asked, "Where can we find water?" She replied, "I was there (at the place of water) this hour yesterday and my people are behind me." They requested her to accompany them. She asked, "Where?" They said, "To Allah's Apostle ." She said, "Do you mean the man who is called the
Sabi', (with a new religion)?" They replied, "Yes, the same person. So come along." They brought her to the Prophet and narrated the whole story. He said, "Help her to dismount." The Prophet asked for a pot, then he opened the mouths of the bags and poured some water into the pot. Then he closed the big openings of the bags and opened the small ones and the people were called upon to drink and water their animals. So they all watered their animals and they (too) all quenched their thirst and also gave water to others and last of all the Prophet gave a pot full of water to the person who was
junub and told him to pour it over his body. The woman was standing and watching all that which they were doing with her water. By Allah, when her water bags were returned the looked like as if they were more full (of water) than they had been before (Miracle of Allah's Apostle) Then the Prophet ordered us to collect something for her; so dates, flour and
sawiq were collected which amounted to a good meal that was put in a piece of cloth. She was helped to ride on her camel and that cloth full of food-stuff was also placed in front of her and then the Prophet said to her, "We have not taken your water but Allah has given water to us." She returned home late. Her relatives asked her: "O so and so what has delayed you?" She said, "A strange thing! Two men met me and took me to the man who is called the
Sabi' and he did such and such a thing. By Allah, he is either the greatest magician between this and this (gesturing with her index and middle fingers raising them towards the sky indicating the heaven and the earth) or he is Allah's true Apostle."
Afterwards the Muslims used to attack the pagans around her abode but never touched her village. One day she said to her people, "I think that these people leave you purposely. Have you got any inclination to Islam?" They obeyed her and all of them embraced Islam.
Abu 'Abdultah said: The word
saba'a means "The one who has deserted his old religion and embraced a new religion." Abul 'Ailya said, "The
Sabis are a sect of people of the Scripture who recite the Book of Psalms."
Supplication for Rain
Volume 8, Book 73, Number 115:
Narrated Anas:
A man came to the Prophet on a Friday while he (the Prophet) was delivering a sermon at Medina, and said, "There is lack of rain, so please invoke your Lord to bless us with the rain." The Prophet looked at the sky when no cloud could be detected. Then he invoked Allah for rain. Clouds started gathering together and it rained till the Medina valleys started flowing with water. It continued raining till the next Friday. Then that man (or some other man) stood up while the Prophet was delivering the Friday sermon, and said, "We are drowned; Please invoke your Lord to withhold it (rain) from us" The Prophet smiled and said twice or thrice, "O Allah! Please let it rain round about us and not upon us." The clouds started dispersing over Medina to the right and to the left, and it rained round about Medina and not upon Medina. Allah showed them (the people) the miracle of His Prophet and His response to his invocation.
Crying of the stem of the Date-palm Tree
Volume 4, Book 56, Number 783:
Narrated Ibn Umar:
The Prophet used to deliver his sermons while standing beside a trunk of a datepalm. When he had the pulpit made, he used it instead. The trunk started crying and the Prophet went to it, rubbing his hand over it (to stop its crying).
Glorification of Allah by the Prophet's meals
Volume 4, Book 56, Number 779:
Narrated 'Abdullah:
We used to consider miracles as Allah's Blessings, but you people consider them to be a warning. Once we were with Allah's Apostle on a journey, and we ran short of water. He said, "Bring the water remaining with you." The people brought a utensil containing a little water. He placed his hand in it and said, "Come to the blessed water, and the Blessing is from Allah." I saw the water flowing from among the fingers of Allah's Apostle, and no doubt, we heard the meal glorifying Allah, when it was being eaten (by him).
The expulsion of a liar's corpse by the Earth
Volume 4, Book 56, Number 814:
Narrated Anas:
There was a Christian who embraced Islam and read
Surat-al-Baqara and
Al-Imran, and he used to write (the revelations) for the Prophet. Later on he returned to Christianity again and he used to say: "Muhammad knows nothing but what I have written for him." Then Allah caused him to die, and the people buried him, but in the morning they saw that the earth had thrown his body out. They said, "This is the act of Muhammad and his companions. They dug the grave of our companion and took his body out of it because he had run away from them." They again dug the grave deeply for him, but in the morning they again saw that the earth had thrown his body out. They said, "This is an act of Muhammad and his companions. They dug the grave of our companion and threw his body outside it, for he had run away from them." They dug the grave for him as deep as they could, but in the morning they again saw that the earth had thrown his body out. So they believed that what had befallen him was not done by human beings and had to leave him thrown (on the ground).
