Which is better: praying two voluntary rak'ahs at night or during the day?

Question : If someone asks which is better: praying two rak'ahs at night as a purely voluntary prayer, or two rak'ahs during the day?

Answer : We said: at night. Night begins from the setting of the sun. So, for example, praying between Maghrib and 'Isha' is better than praying between Zuhr and 'Asr, because it is a night prayer, and therefore it is better.
