The authentic hadith of Ibn Mas'ud with a sound chain of narration, and a discussion of it from the perspective of the chain.

The Shaykh : Then he narrates with a sound chain—also—from 'Abdullah, who is also our aforementioned companion, Ibn Mas'ud (may Allah be pleased with him). I say this because there are many 'Abdullahs around whom many of the authentic Prophetic hadiths revolve. One of them is 'Abdullah ibn 'Abbas, and we have 'Abdullah ibn 'Umar, and we have 'Abdullah ibn 'Amr ibn al-'As, and we have 'Abdullah ibn 'Abbas, and we have 'Abdullah ibn al-Zubayr, and we have many 'Abdullahs who are not as famous as these. Therefore, it is necessary to specify who 'Abdullah is by the chain of narration so that we are certain about the attribution of the hadith. If it is said that al-Bukhari narrated in *Al-Adab al-Mufrad* from 'Abdullah ibn Mas'ud the previous hadith: , al-Bukhari narrated from 'Abdullah, who is 'Abdullah? We say: it is Ibn Mas'ud. Here it says he narrated with his chain from 'Abdullah, who said: , who is this 'Abdullah? Likewise, it is 'Abdullah ibn Mas'ud.
It may come up, near or far, that we will say: it is 'Abdullah ibn 'Umar or someone else. This is known from the science of al-jarh wa al-ta'dil (the critique and vindication of narrators); that is, the biographies of the men of hadith. In the previous case—there is no harm in pointing this out, even though most of the attendees are women and this science related to hadith is not their primary concern—in the previous hadith, 'Abd al-Rahman ibn Yazid narrated the hadith from 'Abdullah, and from him his son Muhammad, because he narrated it with the chain from Muhammad ibn 'Abd al-Rahman ibn Yazid from his father; meaning 'Abd al-Rahman ibn Yazid from 'Abdullah. The one who narrates from 'Abdullah ibn Mas'ud is this 'Abd al-Rahman ibn Yazid, the Kufi. He is famous for narrating from 'Abdullah ibn Mas'ud, and not as famous for narrating from the other 'Abdullahs.
As for our hadith now, Abu al-Ahwaz narrates it from him, from 'Abdullah. Likewise, Abu al-Ahwaz is the Kufi who frequently narrates from 'Abdullah ibn Mas'ud. By these indications, we discover the identity of the Companion from whom the hadith was narrated. So, 'Abdullah here is 'Abdullah ibn Mas'ud (may Allah be pleased with him), except that this hadith is not marfu' (a report traced to the Prophet) to the Messenger (peace and blessings be upon him), but rather it is from the saying of Ibn Mas'ud himself.
