Musnad Abu Ya'la al-Mawsili 115:20

Narrated to us ‘Abd al-Wahid, narrated to us Hammad ibn Salamah, from Qatadah, Thabit, and Humayd, from Anas, who said: Prices became high during the time of the Messenger of Allah (may Allah bless him and grant him peace), so they said: "O Messenger of Allah, set prices for us." He said: "Indeed, Allah is the Withholder, the Extender, the Price-Setter, the Provider. And I truly hope that I meet Allah while none of you is seeking from me any injustice regarding a life or wealth."
