Hadith 2381809 - 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».
Hadith.1809 - It is narrated from Ya‘qub ibn Shu‘ayb, who said:
I asked Abu Abdullah (Imam Jafar ibn Muhammad Al-Sadiq (as)) about fasting on the Day of Arafah.
Imam (as) said: 'If you wish, you may fast, and if you wish, you may refrain from fasting.'
Imam (as) mentioned: 'A man came to al-Hasan (as) and al-Husayn (as) 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."’"
