'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 Allah'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.
