حَدَّثَنَا مُحَمَّدُ بْنُ سُلَيْمَانَ الْمَالِكِيُّ ، ثنا أَحْمَدُ بْنُ عَبْدَةَ ، ثنا عَبْدُ الْعَزِيزِ بْنُ مُحَمَّدٍ ، أنا قُدَامَةُ بْنُ مُوسَى ، عَنْ مُحَمَّدِ بْنِ الْحُصَيْنِ التَّمِيمِيِّ ، عَنْ أَبِي عَلْقَمَةَ مَوْلَى ابْنِ عَبَّاسٍ ، عَنْ يَسَارٍ مَوْلَى ابْنِ عُمَرَ ، قَالَ : رَآنِي ابْنُ عُمَرَ أُصَلِّي بَعْدَ الْفَجْرِ فَحَصَبَنِي ، وَقَالَ : يَا يَسَارُ ، كَمْ صَلَّيْتَ ؟ قُلْتُ : لا أَدْرِي ، قَالَ : لا دَرَيْتَ ، إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَرَجَ عَلَيْنَا وَنَحْنُ نُصَلِّي هَذِهِ الصَّلاةَ فَتَغَيَّظَ عَلَيْنَا تَغَيُّظًا شَدِيدًا ، ثُمَّ قَالَ : " لِيُبَلِّغْ شَاهِدُكُمْ غَائِبَكُمْ أَنْ لا صَلاةَ بَعْدَ الْفَجْرِ إِلا سَجْدَتَيْنِ " .
Yasar narrates: Once, Abdullah bin Umar (may Allah be pleased with them both) saw me performing (nafl) prayer after the true dawn had appeared, so he threw pebbles at me and said: "O Yasar! How many rak'ahs have you performed?" I replied: I do not remember. So he said: "You do not understand. Once, the Prophet Muhammad (peace and blessings be upon him) came to us while we were performing this prayer (i.e., nafl at this time), and the Prophet (peace and blessings be upon him) expressed intense displeasure at us and said: Let all those present convey this to those who are absent: After the true dawn has appeared, only two rak'ahs (of sunnah) may be performed."
