Musnad Abu Ya'la al-Mawsili 252:25

Dāwūd ibn ‘Amr ibn Zuhayr al-Ḍabbī narrated to us, Zuhayr ibn ‘Amr ibn Ma‘bad al-Taymī narrated to us, from Abū Ḥāzim, from Sahl ibn Sa‘d al-Sā‘idī, who said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "A space the size of a whip in Paradise is better than the world and what is in it. And a morning journey in the path of Allah, or an evening journey, is better than the world and what is in it."
