Is it preferable to give Sadaqa during the last ten days of Ramadan, or is the excellence therein limited to spending the nights in prayer and remembrance?

A Muslim revives the last ten nights of Ramadan with prayer and remembrance. Charity in Ramadan is better than in other months. The virtue of good deeds increases when they occur in a blessed time, such as the nights of the last ten days. One should generally give abundant charity in Ramadan.
