Bukhari

Hadith Commentary:
Hazrat Abdullah ibn Mas'ud radi Allahu anhu described his actual state; although there is a virtue implied in it, his intention was neither pride nor arrogance. However, to say such a thing out of pride and arrogance is prohibited.
“Innamal a‘malu bin-niyyat” (Actions are only by intentions).
The statement of Shaqiq is worthy of consideration, because Ibn Abi Dawud narrated from Zuhri, who said that Mujahid did not approve of this statement of Hazrat Ibn Mas'ud radi Allahu anhu (Wahidi).
It is true.
﴿And above every possessor of knowledge is one [more] knowing﴾

Hadith Commentary:
➊
Abdullah ibn Mas'ud radi Allahu ta'ala anhu has described his actual state. There was no expression of pride or arrogance in his intention, as he himself clarified that he is not the best among the Companions radi Allahu anhum ajma'in. However, the statement of Shaqiq rahimahullah is open to consideration, because Imam Zuhri rahimahullah has stated that the Companions of the Messenger of Allah sallallahu alayhi wa sallam did not like this statement of Abdullah ibn Mas'ud radi Allahu ta'ala anhu. It is possible that this was due to a difference in perspective.

➋
Indeed, Abdullah ibn Mas'ud radi Allahu ta'ala anhu was a scholar of the Noble Qur'an and an excellent reciter, but he insisted on retaining his own codex (mushaf) in comparison to the Uthmani codex. The Companions radi Allahu anhum ajma'in did not approve of this, even though there had already been consensus among all the Companions radi Allahu anhum ajma'in on the codex of Uthman radi Allahu ta'ala anhu.

Benefits and Issues:
➊ The emergence of the Khawarij has occurred in various eras and will continue to occur in the future. They commit extremism in the name of the Qur’an. In their first emergence, they raised the slogan “Inil hukmu illa lillah” (“The judgment is only for Allah” ) and rebelled against Ali radi Allahu anhu and Muawiyah radi Allahu anhu.

➋ (Al-harbu khud‘ah)
War is a stratagem and a secret tactic.
The group or party that adopts a better stratagem and excellent planning becomes successful. One should never be heedless of the enemy’s stratagem and planning, just as nowadays Muslims, by being heedless of the schemes of the Jews and Hindus, have fallen into their trap.
