Musnad Ahmad 947:4

'Abd al-Razzaq and Ibn Bakr narrated to us, Ibn Jurayj informed us, 'Abd Allah ibn 'Uthman informed me, from Nafi' ibn Sarjas, who said: We visited Abu Waqid al-Bakri—and Ibn Bakr said: al-Badri—during the illness in which he died. He heard him say: "The Prophet, peace and blessings of Allah be upon him, was the lightest of people in prayer for the people, and the longest of people in prayer for himself."
