From Sahih Bukhari (Hadith 1628):
Narrated `Urwa from Aisha:Some people performed Tawaf (of the Ka`ba) after the morning prayer and then sat to listen to a preacher till sunrise, and then they stood up for the prayer. Then Aisha commented, "Those people kept on sitting till it was the time in which the prayer is disliked and after that they stood up for the prayer
