Musnad Ahmad 124:10

Yunus ibn Muhammad narrated to us, he said: Al-Ataf ibn Khalid narrated to us, Abu Hazim narrated to us, he said: I heard Sahl ibn Sa’d, he said: I heard the Messenger of Allah, peace and blessings of Allah be upon him, while he was saying: "A morning journey in the way of Allah is better than the world and what is in it. And an evening journey in the way of Allah is better than the world and what is in it. And the space of a whip in Paradise is better than the world and what is in it."
