Sahih Muslim Book - 6, Hadith - 1761

حَدَّثَنَا خَلَفُ بْنُ هِشَامٍ وَأَبُو كَامِلٍ قَالاَ حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ عَنْ أَنَسِ بْنِ سِيرِينَ قَالَ سَأَلْتُ ابْنَ عُمَرَ قُلْتُ أَرَأَيْتَ الرَّكْعَتَيْنِ قَبْلَ صَلاَةِ الْغَدَاةِ أَأُطِيلُ فِيهِمَا الْقِرَاءَةَ قَالَ كَانَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- يُصَلِّى مِنَ اللَّيْلِ مَثْنَى مَثْنَى وَيُوتِرُ بِرَكْعَةٍ - قَالَ - قُلْتُ إِنِّى لَسْتُ عَنْ هَذَا أَسْأَلُكَ. قَالَ إِنَّكَ لَضَخْمٌ أَلاَ تَدَعُنِى أَسْتَقْرِئُ لَكَ الْحَدِيثَ كَانَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- يُصَلِّى مِنَ اللَّيْلِ مَثْنَى مَثْنَى وَيُوتِرُ بِرَكْعَةٍ وَيُصَلِّى رَكْعَتَيْنِ قَبْلَ الْغَدَاةِ كَأَنَّ الأَذَانَ بِأُذُنَيْهِ. قَالَ خَلَفٌ أَرَأَيْتَ الرَّكْعَتَيْنِ قَبْلَ الْغَدَاةِ وَلَمْ يَذْكُرْ صَلاَةِ.

It was narrated that Anas bin Sirin said: "I asked Ibn 'Umar: 'Do you think that in the two Rak'ah before Al-Ghadah (Fajr) prayer I should recite for a long time?' He said: 'The Messenger of Allah (s.a.w) used to pray two by two at night, then he would pray Witr with one Rak'ah. He said: 'It is not about this that I was asking.' He said: 'You are dense. Why don't you let me narrate the Hadith in full? The Messenger of Allah (s.a.w) used to pray two by two at night, then he would pray Witr with one Rak'ah, then he would pray two Rak'ah before Al-Ghadah (Fajr) as if the Iqamah was in his ears."' Khalf (one of the narrators) said: "Before Al-Ghadah" and he did not mention: "prayer."
