this is the month when we should try to help the poor people as much as we can. Our Beloved Rasool Muhammad SAW also used to do more charity during Ramadan as compared to any other month of the year. there will be many needy people around you who don't have food to eat or clothes to wear. its the best time to help them. even if you don't have much money you can help them with less money. its better than not doing anything at all for them.
you can also donate to genuine organizations which are providing food and other things to Muslims In Syria, Burma, Gaza and other countries.
Remember charity is a great deed in our Deen whose virtue increase even more in this blessed month. Our Beloved Rasool SAW has said that:
The believer's shade on the Day of Resurrection will be his charity.and Allah SWT says in the Holy Quran al-Baqarah 2:267
Believe in Allah and His Messenger (Muhammad), and spend of that whereof He has made you trustees. And such of you as believe and spend (in Allah’s way), theirs will be a great reward.
