Musnad Ahmad 32:1255

'Abd al-Samad narrated to us, Abu Hilal narrated to us, from Qatadah, from Anas, that 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: "And how does he hasten?" He said: "He says: 'I have called upon my Lord, and He has not answered me.'"
