English translation
[34] It was narrated by Sufyân [bin 'Uyaynah] who said: "They informed me about Abû 'Aqîl, the companion of Buhayyah; that a son of 'Abdullâh bin 'Umar was asked about something of which he did not have any knowledge. Yahyâ bin Sa'eed said to him: 'I feel it is very grave that a man like you, who is the son of two Imâm of guidance' - meaning 'Umar and Ibn 'Umar - 'can be asked about something of which he has no knowledge.' He said: 'By Allâh, it is more serious than that before Allâh and before anyone who has any knowledge of Allâh, to speak without knowledge, or to narrate from someone who is not trustworthy.' Abû 'Aqîl Yahyâ bin Al-Mutawakkil was present while the two of them said that."
