It is recommended (sunnah) to break ones fast quickly, after one is sure that the maghrib has begun. It is good to break one’s fast on dates, and if not available then by drinking water. As well, it is good to delay suhur meal until a time close to the dawn, but to stop eating before the dawn.
Refraining from backbiting or cursing a Muslim and other sins, and the like is more emphasized while fasting. In committing some of sins, the reward of one’s fasting might be lessened or lost. If someone curses another, let him abstain from responding by a similar curse. Let him say, "I am fasting. I am fasting."

Paying the optional charity to the poor, reciting the Qur’an, staying in the mosque with the intention of i^tikaf, especially during the last ten days of Ramadan, praying the tarawih prayer, and inviting others to break their fast on food which you provided are all rewardable acts.

The month of Ramadan is a great opportunity for the person to gain a lot of reward; reward earned because of performing this obligation in worship and obedience to Allah, and by performing a lot of the sunnah deeds. Let the person not waste his time during this month.
