Musnad Ahmad 32:2113

'Affan narrated to us, Hammad ibn Salamah narrated to us, he said: Qatadah, Thabit, and Humayd informed us, from Anas ibn Malik, who said: Prices became high in Medina during the time of the Messenger of Allah, may Allah bless him and grant him peace. The people said: "O Messenger of Allah, prices have become high, so set prices for us." The Messenger of Allah, may Allah bless him and grant him peace, said: "Indeed, Allah is the Price-Setter, the Withholder, the Extender, the Provider. I truly hope that I meet Allah while none of you seeks from me an injustice regarding blood or wealth."
