It is narrated from Hazrat Mutalib that he invited a Bedouin to eat after the day of Eid al-Adha. The Bedouin said, "I am fasting." So Hazrat Mutalib said, "Indeed, I heard Sayyiduna Abdullah bin Umar (may Allah be pleased with them) saying that I heard the Messenger of Allah (peace and blessings be upon him) forbidding fasting on these days."

It is narrated from Abu Murrah, the freed slave of Aqeel, that he and Abdullah presented themselves before Sayyiduna Amr bin Al-Aas (may Allah be pleased with him) on the second or third day of Eid al-Adha. Sayyiduna Amr (may Allah be pleased with him) offered them food, so Abdullah said, "I am fasting." Sayyiduna Amr (may Allah be pleased with him) said to him, "Break your fast. Indeed, the Messenger of Allah (peace and blessings be upon him) used to command not to fast on these days and forbade fasting on these days." Upon this, Abdullah broke his fast and ate the food, and I also ate with him.

Hazrat Mutarrif narrates from his father that the Prophet Muhammad (peace be upon him) said: "Whoever fasted for his entire life, he neither fasted nor left fasting — or he neither fasted nor left fasting."

Sayyiduna Imran bin Husayn (may Allah be pleased with him) narrates that it was said to the Messenger of Allah (peace and blessings be upon him) that a certain person always fasts during the day. The Messenger of Allah (peace and blessings be upon him) said: "He neither fasted nor left off fasting." Imam Abu Bakr (may Allah have mercy on him) says that the narration about the prohibition of prayer from Sayyiduna Qatadah (may Allah be pleased with him) from Hazrat Abu’l-‘Aliyah is well-known, but the narration about the prohibition of fasting from his chain is rare (not well-known).

Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Has it not been reported to me that you spend the whole night in voluntary prayer and fast every day?" I replied that I do so. The Prophet (peace and blessings be upon him) said: "Do not do so. If you act like this, your eyes will become weak and sunken, and your soul will become weary and fatigued. Indeed, your soul has a right over you, your family has a right over you, and your eyes have a right over you. Therefore, sleep as well and pray, fast and also leave fasting (on some days)." This is the narration of Abdul Jabbar, and in the narration of Makhzumi, the words "Do not do so" are not present.

Sayyiduna Hamzah bin Amr Aslami (may Allah be pleased with him) narrates that during the blessed time of the Messenger of Allah (peace and blessings be upon him), I used to observe continuous fasting. So I asked, "O Messenger of Allah, indeed I observe continuous fasting without any break, so should I fast while traveling?" The Prophet (peace and blessings be upon him) said: "If you wish, then fast, and if you wish, then do not fast." Imam Abu Bakr (may Allah have mercy on him) says that I have mentioned other chains of this narration at another place.

Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) narrates from the Noble Prophet (peace and blessings be upon him) that he (peace be upon him) said: "For the person who fasts for a lifetime, Hell will be made so narrow for him," and he (peace be upon him) showed the number ninety by knotting his finger.

It is narrated from Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "The person who fasts continuously throughout his life, for him Hell will be made as narrow as this." And the Prophet (peace be upon him) tied a knot in his fingers while making the number ninety. In the narration of Ibn Bazee’, it is mentioned regarding the person who fasts throughout his life, and it is said that he showed by tying a knot of ninety. The Imam says: I heard from Abu Musa, he was saying that Abu Tamimah's name is Tarif bin Mujalid, and he has heard narrations from Muslimah bin Salit and Jahdam Al-Hajimi. Imam Abu Bakr (may Allah have mercy on him) says that only Ibn Abi Adi has narrated this hadith from Qatadah through Sa'id in a musnad form. Imam Abu Bakr (may Allah have mercy on him) says: I asked Imam Muzani (may Allah have mercy on him) about the meaning of this hadith, so he said: It is possible that its meaning is that Hell will be made narrow for this person, therefore he will not enter Hell, and apart from this, it cannot have any other meaning, because the person who does more deeds for the sake of Allah and advances in obedience and submission, he will have a higher status, honor, dignity, and closeness with Allah. This is the meaning of Imam Muzani's (may Allah have mercy on him) answer.

Hazrat Zarah bin Thawb narrates that I asked Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) about fasting for a lifetime, so he replied that we used to consider such people among us as those who excelled in good deeds. He says, then I asked him about fasting one day and leaving it the next day, so he replied that such a person has not left any fast for the fasting person (as if he has kept all the fasts). And I asked him about keeping three fasts in every month, so he said that such a person has fasted for a lifetime and also left some (i.e., he has both fasted and left fasts).

Abdullah bin Amr al-Qari narrates that Sayyiduna Abu Hurairah (may Allah be pleased with him) was saying while performing Tawaf of the House of Allah: "By the Lord of the Ka'bah, I did not prohibit fasting on Friday. By the Lord of the Ka'bah, Muhammad (peace be upon him) prohibited it." Sa'id has also narrated this report from Yahya bin Ja'dah from Abdullah bin Amr al-Qari, but did not mention the words that he was performing Tawaf of the House of Allah.
