Sahih Muslim · Hadith 1968

حدثنا محمد بن حاتم، حدثنا بهز، حدثنا وهيب، حدثنا عبد الله بن طاوس، عن أبيه، عن عائشة، أنها قالت وهم عمر إنما نهى رسول الله صلى الله عليه وسلم أن يتحرى طلوع الشمس وغروبها ‏.‏

'A'isha said that the Messenger of Allah (may peace be upon him) did not abandon observing two rak'ahs after 'Asr, but she reported Allah's Messenger (may peace be upon him) as saying: Do not get used to observe prayer at the time of the rising sun and at the time of its setting and (exhorted the Muslims) to pray at their times.
