Salam to Abdussalam.
Forgive me for cut and paste as I have not much time these days.
Here I got from one of my favourite websties answering-christianity.com.
1- The Role of the Holy Spirit in Islam:
There are two roles that the Holy Spirit is responsible for according to Islam:
1- It creates our "spirits." Allah Almighty uses it to blow into our mothers' wombs our human-spirits. That is why abortion is prohibited in Islam, because the fetus or foetus does have spirit (life) and it is a human being. It's not just a little piece of unliving flesh:
"But He fashioned him in due proportion, and breathed into him something of His Spirit. And He gave you (the faculties of) hearing and sight and feeling (and understanding): little thanks do ye give! (The Noble Quran, 32:9)"
"When I have fashioned him (in due proportion) and breathed into him of My Spirit, fall ye down in obeisance unto him. (The Noble Quran, 38:72)"
"When I have fashioned him (in due proportion) and breathed into him of My Spirit, fall ye down in obeisance unto him. (The Noble Quran, 15:29)"
"And (remember) her who guarded her chastity: We breathed into her of Our Spirit, and We made her and her son a sign for all peoples. (The Noble Quran, 21:91)"
"And Mary the daughter of 'Imran, who guarded her chastity; and We breathed into (her body) of Our Spirit; and she testified to the truth of the words of her Lord and of His Revelations, and was one of the devout (servants). (The Noble Quran, 66:12)"
2- It is used to provide Divine Guidance to the Believers, those whom Allah Almighty Loves and Favors. It's not just the Holy Spirit that gives Guidance. Angels too give it:
"Raised high above ranks (or degrees), (He is) the Lord of the Throne (of Authority): by His Command doth He send the Spirit (of inspiration) to any of His servants he pleases, that it may warn (men) of the Day of Mutual Meeting,- (The Noble Quran, 40:15)"
"Say, the Holy Spirit has brought the Revelation from thy Lord in Truth, in order to strengthen those who believe, and as a Guide and Glad Tidings to Muslims. (The Noble Quran, 16:102)"
"Thou wilt not find any people who believe in God and the Last Day, loving those who resist God and His Apostle, even though they were their fathers or their sons, or their brothers, or their kindred. For such He has written Faith in their hearts, and strengthened them with a Spirit from Himself. And He will admit them to Gardens beneath which Rivers flow, to dwell therein (for ever). God will be well pleased with them, and they with Him. They are the Party of God. Truly it is the Party of God that will achieve Felicity. (The Noble Quran, 58:22)"
"Then will God say: "O Jesus the son of Mary! Recount My favour to thee and to thy mother. Behold! I strengthened thee with the Holy Spirit, so that thou didst speak to the people in childhood and in maturity. Behold! I taught thee the Book and Wisdom, the Law and the Gospel and behold! thou makest out of clay, as it were, the figure of a bird, by My leave, and thou breathest into it and it becometh a bird by My leave, and thou healest those born blind, and the lepers, by My leave. And behold! thou bringest forth the dead by My leave. And behold! I did restrain the Children of Israel from (violence to) thee when thou didst show them the clear Signs, and the unbelievers among them said: 'This is nothing but evident magic.' (The Noble Quran, 5:110)"
So as you can see, Allah Almighty Created the Holy Spirit for specific functions not only on this earth, but also perhaps else where in the Universe where we don't know about. But it is in no way GOD Almighty Himself.
