Some scholars name the amount as much as three thousand. I'll try to mention some here.
He had water pour form his hands enough for about 1,000 people to perform ablution, to drink and their animals to drink.
He was told that they wouldn't believe unless the moon split into two. He raised his hands and the moon split in two, there is a narration that a king in India saw it and became Muslim after hearing the news of a new religion.
Once a man came with a lizard in his hand and said I wont believe until this lizard believes. The Prophet (peace and blessings be upon) asked the lizard, it said, "I testify there is only one God and that you are his messenger."
Another time, some rocks could be heard praising God in his hand.
During the first 40 days of gestation, all the body parts and organs are completely, though consecutively formed. We can notice in Figure 2.1 that the organs begin to be formed, assembled, and the fetus appears twisted. The Prophet Muhammad, (peace be upon him), has informed us in a hadeeth that: In every one of you, all components of your creation are gathered together in your mothers womb by 40 days. (Narrated in Saheeh Muslim and Al-Bukhaari).
In another Hadeeth, Prophet Muhammad (peace be upon him) said: When forty-two nights have passed over the drop (nutfah), Allah sends an angel to it, who shapes it and makes its ears, eyes, skin, flesh and bones. Then he says, O Lord, is it male or female? and your Lord decides what he wishes. (Muslim).
Professor Simpson studied these two hadeeths extensively, noting that the first 40 days constitute a clearly distinguishable stage of embryo genesis. He was particularly impressed by the absolute precision and accuracy of those hadeeths. Then during one of the conferences which he attended he gave the following opinion: "So that the two hadeeths that have been noted can provide us with a specific time table for the main embryological development before 40 days. Again, the point had been made repeatedly by other speakers this morning that these hadeeths could not have been obtained on the basis of the scientific knowledge that was available at the time of their recording."
Professor Simpson says that religion can successfully guide the pursuit of knowledge. The West, as we said, has rejected this. Here is an American scientist who says that religion, namely Islam, can achieve this with success. By analogy, if you go to a factory and have with you the operation manual of the factory, then you will be able to easily understand the kind of operation that goes on in that factory, thanks to that manual by the factory designer and builder. If you do not have this manual with you, chances are much less that you will have good understanding of the various processes there.
Professor Simpson said: "It follows, I think, that not only is there no conflict between genetics and religion, but in fact religion can guide science by adding revelation to some traditional scientific approaches. That there exist statements in the Qur'an shown by science to be valid, which supports knowledge in the Qur'an having been derived from Allah."
This is true. Certainly, the Muslims can lead the way in the pursuit of knowledge and that they can accord knowledge in its proper status. Moreover, Muslims know how to use knowledge as a proof of the existence of Allah, May Allah be Exalted and Glorified, and to affirm the Messenger ship of Muhammad (peace be upon him).
What else do you need?
Soon will we show them our signs in the (furthest) regions (of the earth), and in their own souls, until it becomes manifest to them that this is the truth. Is it not enough that thy Lord does witness all things? (Qur'an 41:53).
Once someone told him he wouldn't believe unless he saw a miracle. The Prophet (peace and blessings upon him) called a tree, which uprooted itself and came to the Prophet.
Many times, food would be multiplied when he was there
The greatest miracle is the Quran which is in the same language as its revelation and is preserved from all harm.
His guardian Abu Talib noticed that when Muhammad would eat first then the food would be enough for the rest of his family. They were poor, Abu Talib would make Muhammad (peace and blessings be upon him) start first. If they didn’t then the food would not suffice them.
He one went to a companions house, who cooked a small lamb and told him not to look in the pot and keep dishing it out. He did so about 500 people where fed, with the lamb as it was when it was cooked.
Once they had little food, so they gathered their dates and ate from them and the number did not decease.
He used to talk to the Muslim whilst leaning on a tree, when a Muslim woman built him a platform to stand on. The tree began to cry like a baby and he had to hug it to stop, to the companions, it sounded like a baby being comforted.
He predicted future events like the fall of Constantinople to the Muslims.
