Abu Umamah reported: "I came to the [Prophet Muhammad, PBUH] and said: 'Order me to do a deed that will allow me to enter Paradise.' He said: 'Stick to fasting, as there is no equivalent to it.'"
The Prophet Muhammad (peace be upon him) said: "If anyone fasts for a day out of a desire to please God, God will remove that person from (Hell) as far as a crow flies from the time it is a young bird until it dies of old age." Al-Trimidhi
The Prophet Muhammad (peace be upon him) said: "Whoever does a voluntary good deed during this month [Ramadan], it is as if that person performed an obligatory good deed at another time, and whoever performs an obligatory good deed, it is as if that person performed 70 obligatory good deeds at another time."
A rich man once said to the Prophet Muhammad (pbuh): "Tell me how to conduct my life and how to spend (my money)." The Prophet replied: "Give (regular charity) out of your property, for truly it is a purifier, and be kind to your relatives and acknowledge the rights of the poor, neighbors and (those in need who seek your help)."
