Sunan an-Nasa'i, Volume 1, Book 6, Hadith 526 (DarusSalam)

Sayyar bin Salamah said: "I entered upon Abu Barzah, and my fatehr asked him: 'How did the Messenger of Allah pray the prescribed prayers?' He said: 'He used to pray Zuhr, which you call Al-Uula (the first) when the sun passed its zenith; he used to pray 'Asr when one of us could go back to his hoome in the farthest part of Al-Madinah while the sun was still bright.' I forgot what he said about Maghrib. 'And he used to like to delay 'Isha', which you call Al-'Atamah, and he did not like to sleep before it nor talk after it. And he used to finish the Al-Ghadah (Fajr) prayer when a man could recognize his neighbor, and he used to recite (in it) between sixty and one hundred verses.'"

أَخْبَرَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ حَدَّثَنَا يَحْيَى، قَالَ حَدَّثَنَا عَوْفٌ، قَالَ حَدَّثَنِي سَيَّارُ بْنُ سَلاَمَةَ، قَالَ دَخَلْتُ عَلَى أَبِي بَرْزَةَ فَسَأَلَهُ أَبِي كَيْفَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يُصَلِّي الْمَكْتُوبَةَ قَالَ كَانَ يُصَلِّي الْهَجِيرَ الَّتِي تَدْعُونَهَا الأُولَى حِينَ تَدْحَضُ الشَّمْسُ وَكَانَ يُصَلِّي الْعَصْرَ حِينَ يَرْجِعُ أَحَدُنَا إِلَى رَحْلِهِ فِي أَقْصَى الْمَدِينَةِ وَالشَّمْسُ حَيَّةٌ وَنَسِيتُ مَا قَالَ فِي الْمَغْرِبِ وَكَانَ يَسْتَحِبُّ أَنْ يُؤَخِّرَ الْعِشَاءَ الَّتِي تَدْعُونَهَا الْعَتَمَةَ وَكَانَ يَكْرَهُ النَّوْمَ قَبْلَهَا وَالْحَدِيثَ بَعْدَهَا وَكَانَ يَنْفَتِلُ مِنْ صَلاَةِ الْغَدَاةِ حِينَ يَعْرِفُ الرَّجُلُ جَلِيسَهُ وَكَانَ يَقْرَأُ بِالسِّتِّينَ إِلَى الْمِائَةِ ‏.‏
