People like to give charity in Ramadan due to the extra blessings they hope to receive during that most special month of the year. However, this does not mean we should withhold giving a needy person charity right now. That would be a mistake. We receive blessings for hastening our good deeds.
The needy person is presently in need. Therefore it is best to fulfill that need as quickly as you can. Do not postpone giving charity.
We should always hasten to perform good deeds.
Allah says: "And hasten to forgiveness from your Lord; and a Garden, the extensiveness of which is (as) the heavens and the earth, prepared for those who guard (against evil). Those who spend (freely), whether in prosperity, or in adversity; who restrain anger, and pardon (all) people – for Allah loves those who do good." [Sûrah Al `Imrân: 132-133]
However, in Ramadan, you should hasten in giving more charity – even by paying your Zakâh early, before it is actually due, and not postponing it until after Ramadan.
And Allah knows best.
