[Machine] Umar delivered a sermon to us from the pulpit of the Messenger of Allah ﷺ , and Ali said, "Ubayy is our most knowledgeable, and Ubayy is our best reciter. We leave nothing from Ubayy's statement, and Ubayy heard certain things from the Messenger of Allah ﷺ that I did not. Ubayy says, 'I do not leave anything that I have heard from the Messenger of Allah ﷺ ,' and after Ubayy, a book was revealed, containing the narration of Abu Ayyub al-Ansari from Ubayy bin Ka'b."  

خَطَبَنَا عُمَرُ عَلَى مِنْبَرِ رَسُولِ اللهِ ﷺ فَقَالَ عَلِيٌّ أَقْضَانَا وَأُبَيٌّ أَقْرَؤُنَا وَإِنَّا لَنَدَعُ مِنْ قَوْلِ أُبَيٍّ شَيْئًا وَإِنَّ أُبَيًّا سَمِعَ مِنْ رَسُولِ اللهِ ﷺ أَشْيَاءَ وَأُبَيٌّ يَقُولُ لَا أَدَعُ مَا سَمِعْتُ مِنْ رَسُولِ اللهِ ﷺ وَقَدْ نَزَلَ بَعْدَ أُبَيٍّ كِتَابٌ حَدِيثُ أَبِي أَيُّوبَ الْأَنْصَارِيِّ عَنْ أُبَيِّ بْنِ كَعْبٍ
