Musnad Abu Ya'la al-Mawsili 1:73

Ishaq ibn Isma'il al-Taliqani narrated to us, Husayn ibn 'Ali al-Ju'fi narrated to us, from Za'idah, from 'Asim ibn Abi al-Najud, from Abu Salih, who said: Abu Bakr al-Siddiq stood upon the pulpit and delivered a sermon. He praised Allah and extolled Him, then said: "The Messenger of Allah (may Allah bless him and grant him peace) stood among us last year upon this pulpit on a day like this, in a month like this." He then wept and said: "Ask Allah for pardon and well-being."
