سَأَلَ مُحَمَّدُ بْنُ مُسْلِمٍ وَ زُرَارَةُ بْنُ أَعْيَنَ أَبَا جَعْفَرٍ اَلْبَاقِرَ عَلَيْهِ اَلسَّلاَمُ: عَنْ صَوْمِ يَوْمِ عَاشُورَاءَ فَقَالَ «كَانَ صَوْمُهُ قَبْلَ شَهْرِ رَمَضَانَ فَلَمَّا نَزَلَ شَهْرُ رَمَضَانَ تُرِكَ ».
Muhammad ibn Muslim and Zurara ibn A‘yan asked Abu Ja‘far Imam Muhammad ibn Ali Al-Baqir عليه السلام about fasting on the Day of Ashura. Imam عليه السلام said: "Its fasting was practiced before the Month of Ramadan, but when the Month of Ramadan was prescribed, it was abandoned."

The Messenger of Allah سبحانه وتعالى (peace and blessings be upon him and his family) said: "Whoever fasts a day in the way of Allah سبحانه وتعالى, it is equivalent to fasting a whole year."

وَ قَالَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ: «مَا مِنْ صَائِمٍ يَحْضُرُ قَوْماً يَطْعَمُونَ إِلاَّ سَبَّحَتْ لَهُ أَعْضَاؤُهُ وَ كَانَتْ صَلاَةُ اَلْمَلاَئِكَةِ عَلَيْهِ وَ كَانَتْ صَلاَتُهُمُ اِسْتِغْفَاراً».
The Messenger of Allah سبحانه وتعالى (peace and blessings be upon him and his family) said: "No fasting person sits among a group of people who are eating except, that his limbs will glorify Allah سبحانه وتعالى, the angels will send prayers upon him, and their prayers are acts of seeking forgiveness for him."

وَ رُوِيَ عَنْ مُوسَى بْنِ جَعْفَرٍ عَلَيْهِمَا اَلسَّلاَمُ قَالَ: «مَنْ صَامَ أَوَّلَ يَوْمٍ مِنْ عَشْرِ ذِي اَلْحِجَّةِ كَتَبَ اَللَّهُ لَهُ صَوْمَ ثَمَانِينَ شَهْراً فَإِنْ صَامَ اَلتِّسْعَ كَتَبَ اَللَّهُ عَزَّ وَ جَلَّ لَهُ صَوْمَ اَلدَّهْرِ».
It is narrated from Imam Musa ibn Jafar Al-Kadhim عليه السلام who said: "Whoever fasts the first day of the ten days of Dhu al-Hijjah, Allah سبحانه وتعالى will record for him the reward of fasting eighty months. And if he fasts all nine days, Allah سبحانه وتعالى, the Almighty, will record for him the reward of fasting a lifetime."

وَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «صَوْمُ يَوْمِ اَلتَّرْوِيَةِ كَفَّارَةُ سَنَةٍ وَ يَوْمِ عَرَفَةَ كَفَّارَةُ سَنَتَيْنِ.
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "Fasting on the Day of Tarwiyah is an expiation for one year, and fasting on the Day of Arafah is an expiation for two years."

وَ رُوِيَ عَنْ يَعْقُوبَ بْنِ شُعَيْبٍ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَنْ صَوْمِ يَوْمِ عَرَفَةَ قَالَ «إِنْ شِئْتَ صُمْتَ وَ إِنْ شِئْتَ لَمْ تَصُمْ» وَ ذَكَرَ «أَنَّ رَجُلاً أَتَى اَلْحَسَنَ وَ اَلْحُسَيْنَ عَلَيْهِمَا اَلسَّلاَمُ فَوَجَدَ أَحَدَهُمَا صَائِماً وَ اَلْآخَرَ مُفْطِراً فَسَأَلَهُمَا فَقَالاَ «إِنْ صُمْتَ فَحَسَنٌ وَ إِنْ لَمْ تَصُمْ فَجَائِزٌ».
It is narrated from Ya‘qub ibn Shu‘ayb, who said: I asked Abu Abdullah (Imam Jafar ibn Muhammad Al-Sadiq عليه السلام) about fasting on the Day of Arafah. Imam عليه السلام said: 'If you wish, you may fast, and if you wish, you may refrain from fasting.' Imam عليه السلام mentioned: 'A man came to al-Hasan عليه السلام and al-Husayn عليه السلام and found one of them fasting and the other not fasting. He asked them, and they said: "If you fast, it is good, and if you do not fast, it is permissible."’"

وَ رَوَى عَبْدُ اَللَّهِ بْنُ اَلْمُغِيرَةِ عَنْ سَالِمٍ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: «أَوْصَى رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ إِلَى عَلِيٍّ عَلَيْهِ اَلسَّلاَمُ وَحْدَهُ وَ أَوْصَى عَلِيٌّ عَلَيْهِ اَلسَّلاَمُ إِلَى اَلْحَسَنِ وَ اَلْحُسَيْنِ عَلَيْهِمَا اَلسَّلاَمُ جَمِيعاً وَ كَانَ اَلْحَسَنُ عَلَيْهِ اَلسَّلاَمُ إِمَامَهُ فَدَخَلَ رَجُلٌ يَوْمَ عَرَفَةَ عَلَى اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ وَ هُوَ يَتَغَدَّى وَ اَلْحُسَيْنُ عَلَيْهِ اَلسَّلاَمُ صَائِمٌ ثُمَّ جَاءَ بَعْدَ مَا قُبِضَ اَلْحَسَنُ عَلَيْهِ اَلسَّلاَمُ فَدَخَلَ عَلَى اَلْحُسَيْنِ عَلَيْهِ اَلسَّلاَمُ يَوْمَ عَرَفَةَ وَ هُوَ يَتَغَدَّى وَ عَلِيُّ بْنُ اَلْحُسَيْنِ عَلَيْهِمَا اَلسَّلاَمُ صَائِمٌ فَقَالَ لَهُ اَلرَّجُلُ إِنِّي دَخَلْتُ عَلَى اَلْحَسَنِ عَلَيْهِ اَلسَّلاَمُ وَ هُوَ يَتَغَدَّى وَ أَنْتَ صَائِمٌ ثُمَّ دَخَلْتُ عَلَيْكَ وَ أَنْتَ مُفْطِرٌ فَقَالَ «إِنَّ اَلْحَسَنَ عَلَيْهِ اَلسَّلاَمُ كَانَ إِمَاماً فَأَفْطَرَ لِئَلاَّ يُتَّخَذَ صَوْمُهُ سُنَّةً وَ لِيَتَأَسَّى بِهِ اَلنَّاسُ فَلَمَّا أَنْ قُبِضَ كُنْتُ أَنَا اَلْإِمَامَ فَأَرَدْتُ أَنْ لاَ يُتَّخَذَ صَوْمِي سُنَّةً فَيَتَأَسَّى اَلنَّاسُ بِي».
It is narrated by Abdullah ibn al-Mughira from Salim, from Abu Abdullah (Imam Jafar ibn Muhammad Al-Sadiq عليه السلام), who said: "The Messenger of Allah سبحانه وتعالى (peace and blessings be upon him and his family) bequeathed solely to Ali عليه السلام, and Ali عليه السلام bequeathed jointly to al-Hasan عليه السلام and al-Husayn عليه السلام. Al-Hasan عليه السلام was the Imam during his time. A man entered upon al-Hasan عليه السلام on the Day of Arafah and found him having lunch, while al-Husayn عليه السلام was fasting. After al-Hasan عليه السلام passed away, the same man entered upon al-Husayn عليه السلام on the Day of Arafah and found him having lunch, while Ali ibn al-Husayn عليه السلام was fasting. The man said to Imam: 'I came to al-Hasan عليه السلام when he was having lunch, and you were fasting. Then I came to you, and now you are not fasting.' Imam عليه السلام replied: 'Al-Hasan عليه السلام was the Imam, so he broke his fast to ensure his fasting would not be taken as a Sunnah and followed by others. When he passed away, I became the Imam, and I did not want my fasting to be taken as a Sunnah and followed by others.'"

وَ رَوَى حَنَانُ بْنُ سَدِيرٍ عَنْ أَبِيهِ قَالَ: سَأَلْتُهُ عَنْ صَوْمِ يَوْمِ عَرَفَةَ فَقُلْتُ جُعِلْتُ فِدَاكَ إِنَّهُمْ يَزْعُمُونَ أَنَّهُ يَعْدِلُ صَوْمَ سَنَةٍ قَالَ «كَانَ أَبِي عَلَيْهِ اَلسَّلاَمُ لاَ يَصُومُهُ» قُلْتُ وَ لِمَ جُعِلْتُ فِدَاكَ قَالَ « يَوْمُ عَرَفَةَ يَوْمُ دُعَاءٍ وَ مَسْأَلَةٍ فَأَتَخَوَّفُ أَنْ يُضْعِفَنِي عَنِ اَلدُّعَاءِ وَ أَكْرَهُ أَنْ أَصُومَهُ وَ أَتَخَوَّفُ أَنْ يَكُونَ يَوْمُ عَرَفَةَ يَوْمَ اَلْأَضْحَى وَ لَيْسَ بِيَوْمِ صَوْمٍ.
It is narrated by Hanan ibn Sudayr from his father, who said: "I asked him about fasting on the Day of Arafah, and I said: 'May I be your ransom, they claim that fasting it equals fasting for a year.' Imam عليه السلام said: 'My father عليه السلام would not fast on that day.' I asked: 'Why? May I be your ransom.' Imam عليه السلام said: 'The Day of Arafah is a day of supplication and asking (from Allah سبحانه وتعالى). I fear that fasting might weaken me from making supplications, and I dislike fasting it as I fear that the Day of Arafah may coincide with the Day of Eid al-Adha, which is not a day of fasting.'"

Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "When al-Husayn ibn Ali عليه السلام was martyred, Allah سبحانه وتعالى, the Almighty, commanded an angel to proclaim: 'O oppressive nation, O killers of the progeny of your Prophet صلى الله عليه وعلى آله وسلم, may Allah سبحانه وتعالى not grant you success in fasting or breaking your fast.'"

It is narrated from al-Hasan ibn Ali al-Washa, who said: ‘I was with my father when I was a boy, and we had dinner with Imam Ali ibn Musa Ar-Ridha عليه السلام on the night of the 25th of Dhu al-Qa‘dah.’ Imam عليه السلام said to him: 'The 25th night of Dhu al-Qa‘dah is the night on which Ibrahim عليه السلام was born, and on which Isa ibn Maryam عليه السلام was born, and it is the night when the earth was spread out from beneath the Ka‘bah. Whoever fasts on that day, it is as if he has fasted for sixty months.'"

It is narrated: "On the 29th of Dhu al-Qa‘dah, Allah سبحانه وتعالى, the Almighty, sent down the Ka‘bah, which was the first mercy to descend. Whoever fasts on that day, it will be an expiation for seventy years."

It is narrated by al-Hasan ibn Rashid from Abu Abdullah (Imam Jafar ibn Muhammad Al-Sadiq عليه السلام), who said: I said: 'May I be your ransom, is there a festival for Muslims other than the two Eids?' Imam عليه السلام said: 'Yes, O’ Hasan, and it is greater and more noble than them.' I said: 'What day is it?' Imam عليه السلام said: 'It is the day on which Amir al-Mu'minin عليه السلام was appointed as a guide for the people.' I said: 'May I be your ransom, which day is that?' Imam عليه السلام said: 'The days revolve, and it is the 18th of Dhu al-Hijjah.' I said: 'May I be your ransom, what should we do on that day?' Imam عليه السلام said: 'You should fast it, O’ Hasan, and increase your prayers upon Muhammad and his family عليه السلام. You should also declare your disassociation to Allah سبحانه وتعالى, the Almighty, from those who wronged them and usurped their rights. Indeed, the Prophets عليه السلام used to command their successors to designate the day on which the successor was appointed as a festival.' I said: 'What is the reward for fasting it for us?' Imam عليه السلام said: 'The reward of fasting sixty months. Also, do not neglect fasting on the 27th of Rajab, for it is the day on which prophethood was bestowed upon Muhammad صلى الله عليه وعلى آله وسلم (peace and blessings be upon him and his family), and its reward for you is like fasting sixty months.'"

Abu Basir asked Abu Abdullah (Imam Jafar ibn Muhammad Al-Sadiq عليه السلام) about a person observing an optional fast who encounters a need to break it. Imam عليه السلام said: "He has the choice until the time of Asr. If he waits until Asr and then decides to fast without having made the intention earlier, he may still fast that day if he wishes."
