حَدَّثَنَا مُسَدَّدٌ ، حَدَّثَنَا يَحْيَى ، عَنْ عُبَيْدِ اللَّهِ ، حَدَّثَنِي نَافِعٌ ، عَنْ ابْنِ عُمَرَ قَالَ : حَدَّثَتْنِي حَفْصَةُ ، أَنّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ" يُصَلِّي سَجْدَتَيْنِ خَفِيفَتَيْنِ بَعْدَ مَا يَطْلُعُ الْفَجْرُ ".
وَكَانَتْ سَاعَةً لَا أَدْخُلُ فِيهَا عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ

Musaddad narrated to us, Yahya narrated to us, on the authority of Ubayd Allah, Nafi’ narrated to me, on the authority of Ibn Umar, he said: Hafsa narrated to me, that the Prophet, may God’s prayers and peace be upon him He used to “pray two light prostrations after dawn comes.”
There was an hour during which I did not enter upon the Prophet, may God bless him and grant him peace.
