Fasting is a physical and internal struggle for the sake of Allah, whereas prayer is a personal connection with Allah through worshipping and praising him, using prostrations and humble actions culminating in a most intimate dua. The rewards of these acts are immense, yet the rank of the one who fasts and prays is reachable through simply having good character. Never neglect yourself and bettering yourself. Having good character influences your own family, benefits society and saves your soul.
