Haritha b. Wahb told that God's messenger exhorted the people to give sadaqa, for the time was coming when a man would go with his sadaqa and find no one to accept it. A man would say, “If you had brought it yesterday I would have accepted it, but I have no need of it today."
Jabir reported God’s messenger as saying,
"Beware of oppression, for oppression (zulm) will produce excessive darkness (zulumat) on the day of resurrection; and beware of niggardliness, for niggardliness destroyed your predecessor, inducing them to shed one another's blood and to treat things forbidden them as lawful."
Abu Huraira told that when a man asked God’s messenger which sadaqa produced the greatest reward he replied,
“That which you give when you are healthy and inclined to be mean, fearing poverty and hoping for a competence. Do not put it off and then say when you are about to die that you give such and such to so and so and such and such to so and so when it has already become the property of so and so.”*
Abu Huraira reported God’s messenger as saying,
"The niggardly man and the one who gives alms are like two men wearing coats of iron with their hands pressed closely to their breasts and their collar-bones. As often as the one who gives alms does so it becomes expanded for him, but as often as the niggardly man thinks about giving alms it contracts and every ring keeps to its place.”
