The Reward of person who helps widows. In Holy Quran

Abu Huraira Radi Allaho Anho reported that Allah's Messenger may peace be upon him said: One who makes efforts (for earning to be spent) on a widow and the destitute ( poor or needy) , is like a striver in the cause of Allah, and I think he also said: He is like one who constantly stands for prayer and observes fast without breaking it.
