Abu Bakr ibn Abi Shaybah narrated to us: Sufyan ibn 'Uyaynah narrated to us, from al-Zuhri, from 'Urwah, from 'A'ishah, who said: The Prophet (peace and blessings be upon him) prayed 'Asr while the sun was in my chamber and its shadow had not yet appeared there.

The source literally says the sun was in her hujrah (private room/chamber); the final clause says the fay' (shadow after the sun's decline) had not yet appeared there.
