Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates: We used to pray behind the Prophet (peace and blessings be upon him) a prayer such that, if one of you were to lead that kind of prayer today, you would find fault with him.
Ahmad recorded it, and its narrators are thiqat (trustworthy).
