Is the following Hadith Qudsi authentic: ((I am Allah; there is no god but I. I am the King of kings and the Possessor of all sovereignty. The hearts of kings are in My hand. If My servants obey Me, I will turn the hearts of their kings towards them))?

The Hadith in question is very weak. It was narrated by Al-Tabarani from Abu Al-Darda, and its chain of narration includes Wahb bin Rashid, who is considered abandoned (matruk), as stated by Al-Haythami. Al-Daraqutni said that Wahb bin Rashid is very weak and his Hadith is abandoned. This Hadith is not authentically attributed to the Prophet (marfu'), and it is more likely that it originates from Malik bin Dinar's readings in books.
