عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ حَفِظْتُ السُّنَّةَ كُلَّهَا غَيْرَ أَنِّي لَا أَدْرِي أَكَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقْرَأُ فِي الظُّهْرِ وَالْعَصْرِ أَمْ لَا وَلَا أَدْرِي كَيْفَ كَانَ يَقْرَأُ هَذَا الْحَرْفَ وَقَدْ بَلَغْتُ مِنَ الْكِبَرِ عُتِيًّا [سورة الشورى: ٤٧] أَوْ عُسِيًّا
It is narrated from Sayyiduna Abdullah bin Abbas, may Allah be pleased with them both, who says: I have memorized all the Sunnahs, except that I do not know whether the Messenger of Allah used to recite (aloud) in the Zuhr and Asr prayers or not. Nor do I know whether he, peace and blessings be upon him, used to recite the word {عُتِیًّا} or {عُسِیًّا} in the verse {وَقَدْ بَلَغْتُ مِنَ الْکِبَرِ عُتِیًّا} (both words mean old age and senility).
