Samurah b. Jundub – Allāh be pleased with him – said:

I was young during the time of Allāh’s Messenger ﷺ and I had memorised things he had said; nothing stopped me from speaking except for the fact that there were amongst us men who were older than me.

Ṣaḥīḥ Muslim, Kitāb Al-Janāʾiz #964.

Al-Ḥasan b. ʿUtaybah reports:

Sufyān Al-Thawrī said to Sufyān b. ʿUyainah, “Why do you not speak (narrate)?” He replied, “While you are alive, no way.”

Al-Khaṭīb Al-Baġdādī, Al-Jāmiʿ li Akhlāq Al-Rāwī #698.

Ḥusayn b. Al-Walīd Al-Naysābūrī said: a reliable person informed me:

ʿAbdullāh b. ʿUmar (Al-ʿUmarī, great-great grandson of ʿUmar) was once asked about something to do with ḥadīth, so he replied, “As long as Abū ʿUthmān (his older brother) is alive, then no.”

Op. cit. #699.

It is reported that ʿĀṣim said:

Zirr (Ibn Ḥubaysh) was older than Abū Wāʾil (Shaqīq b. Salamah); so if they ever sat together [in a gathering] Abū Wāʾil would not speak with Zirr (out of respect).

Op. cit. #702.

It is also reported that:

When Ibrāhīm and Al-Shaʿbī were together, Ibrāhīm would not speak about anything, because of his age.

Op. cit. #703.

It is reported from Abū ʿAbdillāh Al-Muʿayṭī that he said:

I saw Abū Bakr b. ʿAyyāsh in Makkah. Sufyān b. ʿUyainah came to him and knelt in front of him. Abū Bakr asked him, “How are you Sufyān? Sufyān, how is your father’s family?” Then a man came and asked Sufyān about a ḥadīth, so Sufyān said, “Do not ask me as long as this Shaykh is sitting here.”

Op. cit. #705.

It is reported from Al-Ḥasan b. ʿAlī Al-Khallāl that he said:

We were once with Muʿtamir b. Sulaymān while he was speaking to us, when Ibn Al-Mubārak approached. Muʿtamir cut short his speech. It was said to him, “Speak (or narrate) to us.” He replied, “We do not speak in front of our seniors.”

Op. cit. #706.

And it is reported that ʿAbdullāh b. Al-Mubārak was once asked about an issue in the presence of Sufyān b. ʿUyainah, so he replied, “We have been forbidden from speaking in front of our seniors.”
