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. (Using translation from Abū Dāʾūd 1278)
يَا يَسَارُ كَمْ صَلَّيْتَ؟ قُلْتُ لَا أَدْرِي قَالَ لَا دَرَيْتَ إِنَّ رَسُولَ اللهِ ﷺ خَرَجَ عَلَيْنَا وَنَحْنُ نُصَلِّي هَذِهِ الصَّلَاةَ فَقَالَ أَلَا لِيُبَلِّغْ شَاهِدُكُمْ غَائِبَكُمْ أَنْ لَا صَلَاةَ بَعْدَ الصُّبْحِ إِلَّا سَجْدَتَانِ
