Where is the doctrine of Imamat in Quran ?

[One-Truth]

I really do have a problem and wish if any shia can give me a straight answer from the Quran with no interpretations or Hadeeths to the above mentioned questions. Again just from the Quran as Allah (swt) mentioned Salat, Zakat...ect. I would really apprciate if we can have a nice discussion to find the truth of the matter and I thank you very much in advance.

Pharess,
Can you elaborate on this subject please. I hope that this question will raise some bells in some people's brains about Imamat as the shia sees it.
