Sunan Abi Dawud 1278
Narrated Abdullah ibn Umar:
Yasar, the client of Ibn Umar, said: Ibn Umar saw  me praying after the break of dawn. He said: O Yasar, the Messenger of Allah (ﷺ) came to us while we were offering this prayer. He (the Prophet) said: Those who are present should inform those who are absent: Do not offer any prayer after (the break of) dawn except two rak'ahs.
حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ، حَدَّثَنَا وُهَيْبٌ، حَدَّثَنَا قُدَامَةُ بْنُ مُوسَى، عَنْ أَيُّوبَ بْنِ حُصَيْنٍ، عَنْ أَبِي عَلْقَمَةَ، عَنْ يَسَارٍ، مَوْلَى ابْنِ عُمَرَ قَالَ رَآنِي ابْنُ عُمَرَ وَأَنَا أُصَلِّي، بَعْدَ طُلُوعِ الْفَجْرِ فَقَالَ يَا يَسَارُ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم خَرَجَ عَلَيْنَا وَنَحْنُ نُصَلِّي هَذِهِ الصَّلاَةَ فَقَالَ ‏
"‏ لِيُبَلِّغْ شَاهِدُكُمْ غَائِبَكُمْ لاَ تُصَلُّوا بَعْدَ الْفَجْرِ إِلاَّ سَجْدَتَيْنِ ‏"‏ ‏.‏
