From the benefits of Fasting:
{The fasting men and fasting women, the men who guard their private parts and the women who do so, and the men who remember Allah often and the women who do so – for them Allah has prepared forgiveness and a great reward.} [33:35]
The Hadeeth “Whoever fasts a day in the cause of Allah, Allah will move away from him the hellfire the distance of 100 years” (reported by an Nasaa’i).
