Personally, I consider that when a person submits a manuscript to a scientific journal, s/he must not use references of manuscripts that are under submission, irrespective of the journal guidelines to authors. The reasons that a person should avoid to cite works under submission have already been given by the colleagues and I will not be repetitive.
As regards your statement 'I have a paper that i submitted to a conference but it is not yet published, now i have another paper based on the first one and i want to submit it; so i have to wait for the publication of the first one it is more prudent.' (your response, page 1 of the thread), I think that, if the aforementioned first paper is not at the stage of submission, but, at least, at the stage of acceptance, there is no problem and you may proceed with the submission of the paper you desire, including in its References section the first paper.
This will depend on the journal. Some have a rule saying they will not except references that are not published. I would recommend checking the guidance for authors to see if they say this. If they dont explicitly say no then it is safe to assume that you can - but it is best to avoid this wherever possible
Dear Sara, I believe that the journal should only be mentioned if the article has been approved for publication. Otherwise, you would be giving information that may be false.
If it is not contradictory to the Editorial policy, give the name of the publication and state the the MS is in press. However, I feel that only accepted papers should be cited.
It depends on your field, the journal you submit your article to and finally on the manuscript itself.
For example, in my field, there is a famous such non-published manuscript, for Prof. G. Hamilton. In his manuscript, he proved a conjuncture posed in 1906. Any mathematician can cite this great non-published work. On the other side, there are too many manuscripts(with arXiv no.) with fatal mistakes.
It is very important to cite only published work, but in special cases you can cite non-published work depending on your field, the journal and the manuscript itself.
References are included to (1) avoid plagiarism and (2) to give readers added information not included in your document. You could publish your article and cite references including the word "submitted". However if your article is published but the submitted article is not, then readers do not have access to the information in the not-submitted article. You have to make the choice. How sure are you that the submitted article or articles will be published.
It depends on your field and the journal you are submitting to. For example, in my field (organizational behavior) such references are not common. However, if the article you want to cite has been presented at a conference, you can cite the conference proceedings.

I have a paper that i submitted to a conference but it is not yet published, now i have another paper based on the first one and i want to submit it; so i have to wait for the publication of the first one it is more prudent. Thank you for your answers.
