What are the best deeds in Ramadan? And what are the best supplications?

The best deeds in Ramadan (definition) are: fasting the entire month, charity and feeding the poor, repentance, reciting the Quran, performing Tarawih prayers, performing Umrah (definition) if possible, and staying in the mosque during the last ten days. As for the best supplications, they are those mentioned in the Quran and Sunnah (definition), such as asking for forgiveness and well-being, Sayyid al-Istighfar (the master of seeking forgiveness), and supplications at the time of breaking the fast and on Laylat al-Qadr (the Night of Power). One should increase in supplication during Ramadan because it is a great season for worship and a time when prayers are answered.
