What is the reward for fasting on Mondays and Tuesdays?

The Prophet, peace and blessings be upon him, encouraged fasting on Mondays and Thursdays. Abu Hurairah reported that the Messenger of Allah, peace and blessings be upon him, said: "Deeds are presented on Monday and Thursday, so I love that my deeds are presented while I am fasting." This indicates an extra reward for these two days, as the virtue of fasting on them is attributed to the presentation of deeds to Allah Almighty. As for fasting on Tuesday, no specific virtue has been reported for it.
