Sahih Al Bukhari – Book of Obligatory Charity Tax (Zakat)

Volumn 002, Book 024, Hadith Number 500.
—————————————–
Narated By Abu Huraira RA: A man came to the Prophet PBUH and asked, "O Allah's Apostle! Which charity is the most superior in reward?" He replied, "The charity which you practice while you are healthy, niggardly and afraid of poverty and wish to become wealthy. Do not delay it to the time of approaching death and then say, 'Give so much to such and such, and so much to such and such.' And it has already belonged to such and such (as it is too late)."

comment: Did you do charity yesterday? did you do charity today? do you do it daily? Make it a habit of giving something in charity on daily basis even if you give 5 ruppees or one meal/food or even an apple to a poor.
