Sayyiduna Abdullah bin Sarjis (may Allah be pleased with him) narrates: The morning prayer was established, and the Messenger of Allah (peace and blessings be upon him) saw a man who was performing the two Sunnah units of Fajr. After finishing the prayer, the Prophet (peace and blessings be upon him) asked him: Which prayer did you consider as the obligatory prayer, the one you performed alone or the one you performed with us?
