Sayyiduna Salamah bin Akwa’ (may Allah be pleased with him) narrated that when this verse was revealed:“Those who have the ability should give a ransom by feeding a poor person”(Al-Baqarah 184), whoever wished would leave fasting and instead give the ransom. This continued until the next verse was revealed:“Whoever among you is present in this month should fast”and it abrogated the previous verse.

Sayyidah Aisha (may Allah be pleased with her) said that if I missed a fast of Ramadan, I would not be able to make it up before Sha'ban.

Narrated by Sayyidah Aisha (may Allah be pleased with her): The Messenger of Allah (peace and blessings be upon him) said, "If a person dies and he had obligatory fasts due, then his guardian should fast on his behalf."

Sayyiduna Abbas (may Allah be pleased with him) narrated that a man came to the Messenger of Allah (peace and blessings be upon him) and said, "O Messenger of Allah, my mother has passed away and she still owed a month of fasting. Can I fast on her behalf to make up for it?" The Prophet replied, "Yes, Allah's debt is more deserving to be fulfilled."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) said: Fasting is a shield for protection from the Fire, so (the fasting person) should neither utter obscene words nor behave ignorantly. And if someone fights with him or abuses him, then his only response should be: "I am fasting" (he should say these words) twice. By the One in Whose hand is my soul, the smell from the mouth of a fasting person is more beloved and purer to Allah than the fragrance of musk. (Allah Almighty says:) My servant leaves his food, drink, and desires for My sake. Fasting is for Me, and I alone will give its reward. (And for other) good deeds, the reward is multiplied tenfold.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) said: Allah Almighty says: Every good deed of the son of Adam is for himself except fasting; it is especially for Me and I alone will give its reward. And fasting is a shield against sins. If any of you is fasting, he should neither use foul language nor raise his voice. If someone abuses him or wants to fight with him, he should simply reply:“I am a fasting person.”By the One in Whose hand is the soul of Muhammad (peace and blessings be upon him), the smell from the mouth of a fasting person is better in the sight of Allah than the fragrance of musk. The fasting person has two joys: (one is) when he breaks his fast, he rejoices, and (the other is) when he meets his Lord, he will be happy with the reward of his fasting.

Sayyiduna Sahl bin Sa’d Sa’idi (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) said: There is a gate in Paradise called Rayyan. On the Day of Resurrection, only those who fast will enter Paradise through it; no one else will enter through it. It will be announced,“Where are those who fasted?”They will stand up, and no one else will be able to enter through it except them. When they have entered, the gate will be closed, and then no one else will be able to enter through it.

Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrated that the Prophet Muhammad (peace and blessings be upon him) used to say: Whoever fasts for one day in the way of Allah (while striving in jihad), Allah Almighty will distance him from Hell by a distance of seventy years.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrated that the Prophet Muhammad (peace and blessings be upon him) said: When someone eats or drinks forgetfully, he should complete his fast, for it is Allah who has fed him and given him drink.

Narrated by Sayyida Aisha (may Allah be pleased with her): When the Messenger of Allah would begin to observe voluntary fasts, we (among ourselves) would say that now he will not stop fasting, and when he would stop fasting, we would say that now he will not fast again. I never saw the Messenger of Allah (peace be upon him) observe voluntary fasts for a whole month except for Ramadan, and I have not seen him fast in any month more than he did in Sha'ban.
