حَدَّثَنَا إِسْمَاعِيلُ أَنْبَأَنَا أَيُّوبُ عَنْ عِكْرِمَةَ قَالَ قَالَ ابْنُ عَبَّاسٍ قَرَأَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِيمَا أُمِرَ أَنْ يَقْرَأَ فِيهِ وَسَكَتَ فِيمَا أُمِرَ أَنْ يَسْكُتَ فِيهِ وَمَا كَانَ رَبُّكَ نَسِيًّا وَ لَقَدْ كَانَ لَكُمْ فِي رَسُولِ اللَّهِ أُسْوَةٌ حَسَنَةٌ
مسند امام احمد بن حنبل · Hadith 3399
Ibn 'Abbas (RA) said: The Messenger of Allah (PBUH) recited (out loud) in that in which he was instructed to recite (out loud) and he recited quietly in that in which he was instructed to recite quietly. "and your Lord is never forgetful" [Maryam 19:64]; "Indeed in the Messenger of Allah (Muhammad (PBUH)) you have a good example to follow" [al-Ahzab 33:21].
