question #3 Sahih Muslim 1011, Book 12, Hadith 74 : How does the hadith emphasize the urgency of charitable acts before a time of abundance?

Give Sadaqa for a time is about to come when a person would walk with alms and the one whom it is to be given would say: Had you brought it yesterday, I would have accepted it. For the present I do not need it. (And the giver of Sadaqa) I would not find anyone to accept it.
