It was one of the miracles with which Allah The Almighty honored His Prophet, , that many of his Companions were cured at his hands. This happened by virtue of his blessing and supplication, something which was highly effective in keeping the Companions steadfast on the religion and in enhancing their faith.

An example of this is what happened with the noble Companion ‘Ali ibn Abi Taalib, may Allah be pleased with him, during the Battle of Khaybar. The Prophet, , said: "I will give the banner to a man at whose hand Allah will grant victory – [a man who] loves Allah and His Messenger, and Allah and His Messenger love him."The Companions spent the whole night wondering who that person would be. In the morning, they went to the Prophet, in order to know the winner of this merit.The Prophet, , asked about ‘Ali ibn Abi Taalib, may Allah be pleased with him, and the Companions told him that he had sore eyes. The Prophet, , sent someone to fetch him. When he came, the Prophet, spat in his eyes and supplicated to Allah for him. Allah The Almighty therefore cured him by virtue of the supplication of the Prophet, . Then Ali, may Allah be pleased with him, took the banner and fought until Allah granted them victory. The complete version of this Hadeeth is narrated in the two books of Saheeh: Al-Bukhari and Muslim.

Even more amazingly, it is narrated on the authority of Qataadah ibn An-Nu‘maan, may Allah be pleased with him, that he fought during the Battle of Uhud until he was hit with an arrow which gouged out one of his eyes. He went to the Prophet, , carrying his eye in his hand. The Prophet, , took it, returned it to its proper place, and supplicated for him. The dislocated eye returned to its natural state and became the more beautiful and the sharper of the two.

One of the miracles of the Prophet, , was the curing of a patient by virtue of blowing a soft breath on him. An example of this happened with the Companion Salamah ibn Al-Akwa‘, may Allah be pleased with him. Yazeed ibn Abi ‘Ubayd said, "I saw the mark of an injury on Salamah's leg. I said to him, 'O Abu Muslim! What is this injury?' He said, 'This is an injury which I suffered on the day of Khaybar, and people said, 'Salamah has been injured.' Then I went to the Prophet and he blew a soft breath on it [the wound] thrice. Since then I have not had any pain in it until this hour.’" [Al-Bukhari]

The miracles of the Prophet, , even exceeded this. He would rub a fracture so that it would be healed. This happened with the Companion ‘Abdullaah ibn ‘Ateek, may Allah be pleased with him. The Prophet, , sent him to kill a Jew by the name of Abu Raafi‘ and his leg had broken during the mission. The Prophet, , asked him to stretch his leg, then he rubbed it. The fracture was healed and ‘Abdullaah, may Allah be pleased with him, could walk with that foot from that very moment. [Al-Bukhari]

Further blessings of the Prophet, , occurred as in the following Hadeeth: As-Saa'ib ibn Yazeed, may Allah be pleased with him, once suffered from a pain. The Prophet, , rubbed his head and supplicated to Allah to bless him. Then, he made ablution, and As-Saa'ib, may Allah be pleased with him, drank from the water used for the ablution. Immediately, the pain disappeared. [Al-Bukhari] Historians mentioned that As-Saa'ib, may Allah be pleased with him, lived until he was ninety years old with perfect health and without experiencing the signs of old age due to the blessing of this supplication of the Prophet, . 

It was narrated on the authority of Jaabir ibn ‘Abdullaah, may Allah be pleased with him, that he contracted a severe disease that caused him to be bed-ridden, and it was so serious that he was not able to recognize those who sat around him. The Prophet, , as well as Abu Bakr As-Siddeeq, may Allah be pleased with him, visited him. The Prophet, , requested water and made ablution with it. He then sprinkled the used water over him. Consequently, he recovered from his disease. [Al-Bukhari and Muslim]

In addition to treating physical diseases, the Prophet, , had an effect in treating psychological diseases as well. It was narrated that a young man went to the Prophet, , and asked him for permission to commit adultery. The Prophet, , put his hand over his chest and supplicated, "O Allah, forgive his sin, purify his heart, and protect his private part." [Ahmad] Accordingly, Allah The Almighty removed the flood of desires from the young man's heart, and he never again looked at women.

These and other situations indicate the supernatural powers and abundant gifts which Allah The Almighty granted to His Prophet, , to support his Da‘wah (call) and to accredit his prophethood.
