(22) باب مِنْ فَضَائِلِ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ وَأُمِّهِ رَضِيَ اللَّهُ تَعَالَى عَنْهُمَا
'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 Mubkmmad (ﷺ) but I did not hear anyone having rejected that (that is, his recitation) or finding fault with it.
