( Ramadan ) Holy spirit in islam?

Many Muslims believe the holy spirit is an angel [Gebril] who was later taeaching Muhamed [PBUH]. Some ppl believe it's special for Isa [Jesus] but in all cases no Muslim think or believes the holy spirit is God. We believe Jesus and the holy spirit are both created by God and not similar to God at all. In Quran also it's written about a quetion from God to Jesus if he has told the ppl to worship him instead of God and Jesus said if I would have said it, you would have known.. you know everything inside me and I don't know. (This is my words of explaination not an accurate tranlation of the meanings as it came in Quran, but you may know this verse.) So I think it's a link between God and his messenger, that link is a creation of God.
