and Yaḥyá ibn Saʿīd is al-Anṣārī al-Najjārī, Abū Saʿīd al-Madanī, the judge. 3 and 4 - As for the ḥadīth of ʿUqbah ibn ʿĀmir and Ḥudhayfah ibn al-Yamān, it is narrated by ʿAmr ibn Shuʿayb that the freedman of Sharḥabīl ibn Ḥasanah informed him that he heard ʿUqbah ibn ʿĀmir and Ḥudhayfah ibn al-Yamān saying: and he mentioned it as marfūʿ. It was recorded by Aḥmad (4/156 and 5/388).
