I heard Abu Umama bin Sahl say, "We prayed Dhuhr with Umar bin Abdul-Aziz, then we went out and entered upon Anas bin Malik, and we found him praying Asr."I asked, "Uncle, what is this prayer you have just prayed?"He replied, "Asr. This is the prayer of the Messenger of Allah ﷺ that we used to pray."
أخبرنا سويد بن نصر قال أنبأنا عبد الله
سمعت أبا أمامة بن سهل يقول صلينا مع عمر بن عبد العزيز الظهر ثم خرجنا حتى دخلنا على أنس بن مالك فوجدناه يصلي العصر قلت يا عم ما هذه الصلاة التي صليت قال العصر وهذه صلاة رسول الله ﷺ التي كنا نصلي
Bukhari included it in the book of the times of prayer, chapter on the time of Asr, hadith no. 549, and Muslim included it in the book of mosques, chapter on the desirability of praying Asr early, hadith no. 623, from the hadith of Abdullah bin Mubarak, with this chain.
