ʿUmar said, Ubai was the best of us in the recitation (of the Qur'an) yet we leave some of what he recites.' Ubai says, 'PI have taken it from the mouth of Messenger of Allah ﷺ and will not leave for anything whatever." But Allah said "None of Our Revelations do We abrogate or cause to be forgotten but We substitute something better or similar." 2.106
عُمَرُ أُبَىٌّ أَقْرَؤُنَا وَإِنَّا لَنَدَعُ مِنْ لَحَنِ أُبَىٍّ وَأُبَىٌّ يَقُولُ أَخَذْتُهُ مِنْ فِي رَسُولِ اللَّهِ ﷺ فَلاَ أَتْرُكُهُ لِشَىْءٍ قَالَ اللَّهُ تَعَالَى {مَا نَنْسَخْ مِنْ آيَةٍ أَوْ نَنْسَأْهَا نَأْتِ بِخَيْرٍ مِنْهَا أَوْ مِثْلِهَا}
