Charity and punishment
It is narrated by Anas bin Malik that the Prophet said: Verily charity appeases the wrath of Allah and eases the sufferings of death. (Tirmidhi)

Women and Charity
Ibn Abbas narrated that the Prophet went out for the Eid prayer on the Eid day and offered a two Rakat prayer; and he neither offered a prayer before it or after it.

One should start giving first to his dependents. And the best object of charity is that which is given by a wealthy person (from the money which is left after his expenses). And whoever abstains from asking others for some financial help, Allah will give him and save him from asking others, Allah will make him self-sufficient. (Bukhari)
