Sayyiduna Abu Hurairah (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said:“Allah Almighty says: For the son of Adam, the reward of a good deed is multiplied from ten to seven hundred times, except for fasting; fasting is for Me and I alone will give its reward, because the fasting person leaves his food and his desires for My sake, he gives up drinking and his carnal desires for My sake, so fasting is for Me and I alone will give its reward.”
