Sunan an-Nasa'i, Book 28, Hadith 21 (In-Book) ⓘ

It was narrated that 'Abdullah bin 'Ubaidullah bin 'Abbas said: I was with Ibn 'Abbas and a man asked him: "Did the Messenger of Allah recite during Zuhr and 'Asr?" He said: "No." He said: "Perhaps he used to recite to himself?" He said: "May your face be scratched! This question is worse than the first one. The Messenger of Allah was a slave whose Lord commanded him and he conveyed (the message). By Allah, the Messenger of Allah did not specify anything for us above the people, except for three things: He commanded us to perform Wudu' properly, not to consume charity, and not to mate donkeys with horses."

أَخْبَرَنَا حُمَيْدُ بْنُ مَسْعَدَةَ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ أَبِي جَهْضَمٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُبَيْدِ اللَّهِ بْنِ عَبَّاسٍ، قَالَ كُنْتُ عِنْدَ ابْنِ عَبَّاسٍ فَسَأَلَهُ رَجُلٌ أَكَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَقْرَأُ فِي الظُّهْرِ وَالْعَصْرِ قَالَ لاَ ‏.‏ قَالَ فَلَعَلَّهُ كَانَ يَقْرَأُ فِي نَفْسِهِ قَالَ خَمْشًا هَذِهِ شَرٌّ مِنَ الأُولَى إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم عَبْدٌ أَمَرَهُ اللَّهُ تَعَالَى بِأَمْرِهِ فَبَلَّغَهُ وَاللَّهِ مَا اخْتَصَّنَا رَسُولُ اللَّهِ صلى الله عليه وسلم بِشَىْءٍ دُونَ النَّاسِ إِلاَّ بِثَلاَثَةٍ أَمَرَنَا أَنْ نُسْبِغَ الْوُضُوءَ وَأَنْ لاَ نَأْكُلَ الصَّدَقَةَ وَلاَ نُنْزِيَ الْحُمُرَ عَلَى الْخَيْلِ ‏.‏
