Yahya related to me from Malik from Nafi from Abdullah ibn Umar that Hafsa, the wife of the Prophet ﷺ told him that the Messenger of Allah ﷺ used to pray two quick rakas when the muadhdhin had finished the adhan for the subh prayer, before the iqama was said for the prayer.  

أَنَّ حَفْصَةَ زَوْجَ النَّبِيِّ ﷺ أَخْبَرَتْهُ أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ إِذَا سَكَتَ الْمُؤَذِّنُ عَنِ الأَذَانِ لِصَلاَةِ الصُّبْحِ صَلَّى رَكْعَتَيْنِ خَفِيفَتَيْنِ قَبْلَ أَنْ تُقَامَ الصَّلاَةُ  

Malik related to me from Yahya ibn Said that A'isha, the wife of the Prophet ﷺ said, "The Messenger of Allah ﷺ used to pray the two rakas of the dawn (fajr) so quickly that I would say to myself 'Has he recited the umm al-Qur'an or not?' "  

أَنَّ عَائِشَةَ زَوْجَ النَّبِيِّ ﷺ قَالَتْ إِنْ كَانَ رَسُولُ اللَّهِ ﷺ لَيُخَفِّفُ رَكْعَتَىِ الْفَجْرِ حَتَّى إِنِّي لأَقُولُ أَقَرَأَ بِأُمِّ الْقُرْآنِ أَمْ لاَ  

Yahya related to me from Malik from Sharik ibn Abdullah ibn Abi Namir that Abu Salama ibn Abd ar-Rahman said, "Some people heard the iqama and started to pray. The Messenger of Allah ﷺ came out and said, 'Are you doing two prayers at the same time? Are you doing two prayers at the same time?' That was about the subh prayer and the two rakas before subh."  

أَنَّهُ قَالَ سَمِعَ قَوْمٌ الإِقَامَةَ فَقَامُوا يُصَلُّونَ فَخَرَجَ عَلَيْهِمْ رَسُولُ اللَّهِ ﷺ فَقَالَ أَصَلاَتَانِ مَعًا أَصَلاَتَانِ مَعًا وَذَلِكَ فِي صَلاَةِ الصُّبْحِ فِي الرَّكْعَتَيْنِ اللَّتَيْنِ قَبْلَ الصُّبْحِ  

Yahya related to me from Malik that he had heard that Abdullah ibn Umar missed the two rakas of dawn, and then did them after the sun rose.  

أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ فَاتَتْهُ رَكْعَتَا الْفَجْرِ فَقَضَاهُمَا بَعْدَ أَنْ طَلَعَتِ الشَّمْسُ  

Yahya related to me from Malik from Abd ar-Rahman ibn al-Qasim that al-Qasim ibn Muhammad had done the same as Ibn Umar.  

أَنَّهُ صَنَعَ مِثْلَ الَّذِي صَنَعَ ابْنُ عُمَرَ
