Sahih Muslim , Hadith 1130

Ibn Abbas (Allah be pleased with both of them) reported that when Allah's Messenger came to Medina, he found the Jews observing the fast on the day of Ashura. They (the Jews) were asked about it and they said: It is the day on which Allah granted victory to Moses and (his people) Bani Isra'il over the Pharaoh and we observe fast out of gratitude to Him. Upon this the Messenger of Allah said: We have a closer connection with Moses than you have, and he commanded to observe fast on this day.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا هُشَيْمٌ، عَنْ أَبِي بِشْرٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ، عَبَّاسٍ - رضى الله عنهما - قَالَ قَدِمَ رَسُولُ اللَّهِ صلى الله عليه وسلم الْمَدِينَةَ فَوَجَدَ الْيَهُودَ يَصُومُونَ يَوْمَ عَاشُورَاءَ فَسُئِلُوا عَنْ ذَلِكَ فَقَالُوا هَذَا الْيَوْمُ الَّذِي أَظْهَرَ اللَّهُ فِيهِ مُوسَى وَبَنِي إِسْرَائِيلَ عَلَى فِرْعَوْنَ فَنَحْنُ نَصُومُهُ تَعْظِيمًا لَهُ ‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ نَحْنُ أَوْلَى بِمُوسَى مِنْكُمْ ‏" ‏ ‏.‏ فَأَمَرَ بِصَوْمِهِ ‏.‏

This hadith has been narrated by Ibn Bishr with the same chain of transmitters (but with a slight variation) that he (the Holy Prophet) inquired of them (Jews) about it (fasting on the day of 'Ashura).

وَحَدَّثَنَاهُ ابْنُ بَشَّارٍ، وَأَبُو بَكْرِ بْنُ نَافِعٍ جَمِيعًا عَنْ مُحَمَّدِ بْنِ جَعْفَرٍ، عَنْ شُعْبَةَ، عَنْ أَبِي بِشْرٍ، بِهَذَا الإِسْنَادِ وَقَالَ فَسَأَلَهُمْ عَنْ ذَلِكَ، ‏.‏

Ibn'Abbas (Allah be pleased with both of them) reported that the Messenger of Allah arrived in Medina and found the Jews observing fast on the day of 'Ashura. The Messenger of Allah said to them: What is the (significance) of this day that you observe fast on it? They said: It is the day of great (significance) when Allah delivered Moses and his people, and drowned the Pharaoh and his people, and Moses observed fast out of gratitude and we also observe it. Upon this the Messenger of Allah said: We have more right, and we have a closer connection with Moses than you have; so Allah's Messenger observed fast (on the day of 'Ashura), and gave orders that it should be observed.

وَحَدَّثَنِي ابْنُ أَبِي عُمَرَ، حَدَّثَنَا سُفْيَانُ، عَنْ أَيُّوبَ، عَنْ عَبْدِ اللَّهِ بْنِ سَعِيدِ بْنِ جُبَيْرٍ، عَنْ أَبِيهِ، عَنِ ابْنِ عَبَّاسٍ، - رضى الله عنهما - أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَدِمَ الْمَدِينَةَ فَوَجَدَ الْيَهُودَ صِيَامًا يَوْمَ عَاشُورَاءَ فَقَالَ لَهُمْ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ مَا هَذَا الْيَوْمُ الَّذِي تَصُومُونَهُ ‏"‏ ‏.‏ فَقَالُوا هَذَا يَوْمٌ عَظِيمٌ أَنْجَى اللَّهُ فِيهِ مُوسَى وَقَوْمَهُ وَغَرَّقَ فِرْعَوْنَ وَقَوْمَهُ فَصَامَهُ مُوسَى شُكْرًا فَنَحْنُ نَصُومُهُ ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ فَنَحْنُ أَحَقُّ وَأَوْلَى بِمُوسَى مِنْكُمْ ‏"‏ ‏.‏ فَصَامَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم وَأَمَرَ بِصِيَامِهِ ‏.‏
