All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad (SAW) is His slave and Messenger.
Before I begin I would like to say that this research was an unbiased research. I started finding about reiki when I heard about it on TV and from people who practice it. I have given account of what is reiki from the sites of institutes of reiki and also from wikipedia.
I begin with verses from the Holy Quran and Hadees of Prophet (saw).
Allah says: And they ask you (o Muhammad (saw)) concerning the ruh (the spirit). Say: “The Ruh (the spirit) is one of the things, the knowledge of which is only with my Lord. And of the knowledge, you (mankind) have been given only a little. “ (Surah 17 Al-Isra , Ayat # 85)
Narrated by Abdullah (Bukhari book 003 hadees 127)
While I was going through the ruins of medina and he was reclining on a date palm leaf stalk, some jews passed by. Some of them said to the others . Ask him (the prophet peaceb upon him) about the spirit. Some of them said that they should not ask him that question as he may might give a reply which would displease them. But some of them insisted on asking, and so one of them stood up and asked, “O abu-al- Qasim! what is the spirit?” The Prophet remained quiet. I thought he was being inspired Divinely Inspired. So i stayed till that state of Prophet ( of being Divinely inspiration) was over. The prophet then recited the above verses. (surah 17, ayat 85).
On the authority of ‘Umar, radiyallahu ‘anhu, who said:
“While we were one day sitting with the Messenger of Allah, sallallahu ‘alayhi wasallam, there appeared before us a man dressed in extremely white clothes and with very black hair. No traces of journeying were visible on him, and none of us knew him.
He sat down close by the Prophet, sallallahu ‘alayhi wasallam, rested his knee against his thighs, and said, O Muhammad! Inform me about Islam.” Said the Messenger of Allah, sallallahu ‘alayhi wasallam, “Islam is that you should testify that there is no deity save Allah and that Muhammad is His Messenger, that you should perform salah (ritual prayer), pay the zakah, fast during Ramadan, and perform Hajj (pilgrimage) to the House (the Ka’bah at Makkah), if you can find a way to it (or find the means for making the journey to it).” Said he (the man), “You have spoken truly.”
We were astonished at his thus questioning him and telling him that he was right, but he went on to say, “Inform me about iman (faith).” He (the Messenger of Allah) answered, “It is that you believe in Allah and His angels and His Books and His Messengers and in the Last Day, and in fate (qadar), both in its good and in its evil aspects.” He said, “You have spoken truly.”
Then he (the man) said, “Inform me about Ihsan.” He (the Messenger of Allah) answered, ” It is that you should serve Allah as though you could see Him, for though you cannot see Him yet He sees you.” He said, “Inform me about the Hour.” He (the Messenger of Allah) said, “About that the one questioned knows no more than the questioner.” So he said, “Well, inform me about the signs thereof (i.e. of its coming).” Said he, “They are that the slave-girl will give birth to her mistress, that you will see the barefooted ones, the naked, the destitute, the herdsmen of the sheep (competing with each other) in raising lofty buildings.” Thereupon the man went off.
I waited a while, and then he (the Messenger of Allah) said, “O ‘Umar, do you know who that questioner was?” I replied, “Allah and His Messenger know better.” He said, “That was Jibril. He came to teach you your religion.””
