Narrated by Sayyiduna Abu Hurairah, may Allah be pleased with him: The Messenger of Allah, peace and blessings be upon him, said: Whoever fasts for one day in the way of Allah, Allah Almighty, in return, will distance him from Hell by a distance of seventy years.

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) has also narrated a similar hadith from the Noble Prophet (peace and blessings of Allah be upon him).

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that at the place of Marr az-Zahran, food was presented to the Noble Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said to Sayyiduna Abu Bakr and Sayyiduna Umar (may Allah be pleased with them): "Come close and eat the food." They said: "We are fasting." The Prophet (peace and blessings be upon him) said: "O people! Give mounts to these companions of yours and do their share of the work as well."

Abu Burdah bin Abi Musa Ash'ari (may Allah be pleased with him) narrates that he and Yazid bin Abi Kabsha were together on a journey. Yazid used to fast during the journey. Sayyiduna Abu Burdah (may Allah be pleased with him) said to him: I have heard Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) narrate many times that the Messenger of Allah (peace and blessings be upon him) said: When a servant becomes ill or is on a journey, he is given the same reward as he used to receive for the deeds he performed while residing and in good health.
