To which Hadith is this statement of Imam Shafi'i attributed?

I have found a statement that Imam Shafi'i would have said: ( سُئل الامام الشافعي رحمه الله تعالى : "كيف يكون سوء الظن بالله؟ قال: الوسوسة، والخوف الدائم من وقوع مُصِيبَة، وترقب زوال النعمة، كلها من سوء الظن بالرحمن الرحيم ) Translation: Imam Shafi'i, rahimullah ta'ala, was asked: 'What is the mistrust of Allah? He said: Waswas, constant fear of calamity, and anticipation of the demise of grace, all of it is mistrust of the Most Merciful, the Most Merciful.' --- On the internet, it is labeled to be a Hadith related in Hilyat al-Awliya with the reference number (9/123), but it is nowhere to be found in the book. Maybe it is a mistake from those who are quoting it, so I would like to ask if somebody has knowledge about this statement, it's source and authenticity?
