Musnad Abu Ya'la al-Mawsili 252:24

Mus'ab narrated to us, Ibn Abi Hazim narrated to us, from Abdullah bin Amir, from Abu Hazim, from Sahl bin Sa'd, who said: I used to eat my Suhur with my family, then there would be haste so that I could catch the prostration with the Messenger of Allah, may Allah bless him and grant him peace.
