'Abdullah (b. Mas'ud) reported that he (said to his companions to conceal their copies of the Qur'an) and further said: He who conceals anything he shall have to bring that which he had concealed on the Day of judgment, and then said: After whose mode of recitation you command me to recite? I in fact recited before AIlah's Messenger ﷺ more than seventy chapters of the Qur'an and the Companions of Allah's Messenger ﷺ know it that I have better understanding of the Book of Allah (than they do), and if I were to know that someone had better understanding than I, I would have gone to him. Shaqiq said: I sat in the company of the Companions of Muhammad ﷺ but I did not hear anyone having rejected that (that is, his recitation) or finding fault with it.
This hadith teaches us to be humble when it comes to our knowledge about Islam, as even though Abdullah bin Mas'ud was knowledgeable in this regard, he still asked for advice from others who may know more than him. It also reminds us to take care when we recite or read from the Quran as we must ensure accuracy in our reading so as not to misquote or misinterpret its teachings. Furthermore, it encourages us to strive for a deeper understanding of Islam by studying its scriptures thoroughly so we can be well-versed in its teachings and practice them accordingly in our lives.
