[Machine] "The Prophet ﷺ prayed in the morning and left out a verse. After praying, he asked, 'Is Ubayy bin Ka'b present among the people?' Ubayy replied, 'Yes, O Messenger of Allah. Was a verse concerning this and that abrogated or forgotten?' The Prophet said, 'It was forgotten.'"  

أحمد:١٥٣٦٥حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنْ سُفْيَانَ حَدَّثَنَا سَلَمَةُ بْنُ كُهَيْلٍ عَنْ ذَرٍّ عَنْ سَعِيدِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ أَبْزَى عَنْ أَبِيهِ

أَنَّ النَّبِيَّ ﷺ صَلَّى فِي الْفَجْرِ فَتَرَكَ آيَةً فَلَمَّا صَلَّى قَالَ أَفِي الْقَوْمِ أُبَيُّ بْنُ كَعْبٍ؟ قَالَ أُبَيٌّ يَا رَسُولَ اللهِ نُسِخَتْ آيَةُ كَذَا وَكَذَا أَوْ نُسِّيتَهَا؟ قَالَ نُسِّيتُهَا
