The Messenger of Allah (may Allah bless him and grant him peace) said:

“Anyone performing a voluntary good deed during it (i.e. Ramadan), it is like one performing an obligatory good deed at another time, and anyone who does an obligatory act during it, it is as if he has done seventy obligatory acts at another time.”

[Part of a longer Hadith related by Imam Al-Bayhaqi]
