1025 - Ishaq narrated to us, saying: Waki' informed us, from Nu'aym ibn Hakim, from Abu Maryam, who said: Al-Hasan ibn Ali led us in one of the daytime prayers; he performed the two prostrations of forgetfulness, although they did not see him forget. When he finished, he said: 'I was conversing with myself.'
1026 - Abbas ibn Abd al-Azim narrated to us, saying: Rawh narrated to us, saying: Ibn Jurayj narrated to us, from Muhammad ibn Yusuf - the freed slave of Amr ibn Uthman - from his father, from Mu'awiyah ibn Abi Sufyan, from the Prophet, peace and blessings of Allah be upon him, who said: 'Whoever is in doubt about anything in his prayer, let him perform the two prostrations of forgetfulness.'
1027 - Abbas narrated to us, saying: Rawh narrated to us, saying: Ibn Jurayj narrated to us, saying: Abdullah ibn Musafi' informed me that Mus'ab ibn Shaybah informed him, from Uqbah ibn Muhammad ibn al-Harith, from Abdullah ibn Ja'far, from the Prophet, peace and blessings of Allah be upon him, who said: 'Whoever is in doubt about anything in his prayer, let him perform the two prostrations of forgetfulness.'
(1) Thus it is in the original, and the correct reading is to omit "Abi".
