Sayyiduna Abu Huraira (may Allah be pleased with him) narrated from the Messenger of Allah (peace and blessings be upon him), he (peace be upon him) said: "The first thing for which a servant will be called to account is his prayer. If he has performed it completely, it is good; otherwise, Allah Almighty will say: Look, does My servant have any voluntary prayers? If his voluntary prayers are found, He will say: Complete his obligatory prayers with them."
