Musnad Ahmad 32:1065

Bahz narrated to us, Abu Hilal narrated to us, Qatadah narrated to us, from Anas, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "The servant will continue to be in a state of goodness as long as he does not hasten." They said: "O Prophet of Allah, how does he hasten?" He said: "He says: 'I called upon my Lord, but He did not answer me.'"
