Musnad Abu Ya'la al-Mawsili 252:2

Ishaq narrated to us, Abd al-Aziz ibn Abi Hazim narrated to us, he said: My father narrated to me, from Sahl ibn Sa'd, that the Messenger of Allah (may Allah bless him and grant him peace) said: "The people will remain in goodness as long as they hasten the breaking of the fast."
