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 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.”
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."
Abu Umama reported God’s messenger as saying,
"Son of Adam, to give away what you have extra is better for you and to withhold it is worse for you, but you are not blamed for having a sufficiency. Give first to those who are dependent on you.”
