I (Ibn ʿAbbās) had memorized all of the Sunnah (traditions) except that: (1) I do not know whether or not the Messenger of Allah ﷺ recited ˹anything˺ in Ẓuhr or ʿAṣr, and (2) I do not know how he used to recite this ḥarf: "and I have reached an old age..." ʿutiyyan or ʿusuyyan.
قَدْ حَفِظْتُ السُّنَّةَ كُلَّهَا غَيْرَ أَنِّي لَا أَدْرِي أَكَانَ رَسُولُ اللهِ ﷺ يَقْرَأُ فِي الظُّهْرِ وَالْعَصْرِ أَمْ لَا وَلا أَدْرِي كَيْفَ كَانَ يَقْرَأُ هَذَا الْحَرْفَ {وَقَدْ بَلَغْتُ مِنَ الكِبَرِ عُتِيًّا} أَوْ {عُسُيًّا}۔
