Sayyar bin Salamah said:
"I entered upon Abu Barzah, and my fatehr asked him: 'How did the Messenger of Allah (ﷺ) 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.'"
