It is reported about Sayyiduna Anas bin Malik (may Allah be pleased with him) that he used to act contrary to Umar bin Abd al-Aziz. Umar bin Abd al-Aziz said to him: What makes you do this? He said: I saw the Prophet (peace and blessings be upon him), how he used to pray. So when you pray in accordance with (the practice of) the Prophet (peace and blessings be upon him), I pray behind you, and when you pray contrary to the way of the Prophet (peace and blessings be upon him), I pray (by myself) and go back to my home.
Ahmad recorded it, and its narrators are thiqat (trustworthy).
