What did the Prophet Muhammad (peace be upon him) say about giving Sadaqa before it becomes too late?
 Haritha b. Wahb reported Allah's Messenger (may peace be upon him) as saying:                      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.
