In Maraqi al Falah it is mentioned:

A group of scholars said that there is nothing specific for the supplication. The best is that he reads, after the preceding supplication, the witr supplication of Hasan ibn ‘Ali, Allah be pleased with them both, who said, “The Messenger of Allah, upon him be blessings and peace, taught me words that I read in witr” – and in one wording “in the witr supplication” – Hakim narrated it. In it he said, “When I raise my head and only prostration remains, “Allah, guide me with those who You have guided....”

I did want to ask what did Hakim narrated precisely i.e. “When I raise my head and only prostration remains, “Allah, guide me with those who You have guided....”

Can someone post the text of the above ahadith and its versions ? Is there proof in this that this duaa should be read after the ruku ? Or is it after the first sajdah when only prostaration remains ? Or what is ment with the sentence: “When I raise my head and only prostration remains...” ?
