ʿUmar said, "Our best Qur'an reciter is Ubai and our best judge is ʿAli; and in spite of this, we leave some of the statements of Ubai because Ubai says, 'I do not leave anything that I have heard from Messenger of Allah ﷺ while Allah: "Whatever verse (Revelations) do We abrogate or cause to be forgotten but We bring a better one or similar to it." (2.106)
عُمَرُ ؓ أَقْرَؤُنَا أُبَىٌّ وَأَقْضَانَا عَلِيٌّ وَإِنَّا لَنَدَعُ مِنْ قَوْلِ أُبَىٍّ وَذَاكَ أَنَّ أُبَيًّا يَقُولُ لاَ أَدَعُ شَيْئًا سَمِعْتُهُ مِنْ رَسُولِ اللَّهِ ﷺ وَقَدْ قَالَ اللَّهُ تَعَالَى {مَا نَنْسَخْ مِنْ آيَةٍ أَوْ نَنْسَأْهَا}
