When the Prophet ﷺ arrived at Medina he found that the Jews observed fast on the day of 'Ashura'. They were asked the reason for the fast. They replied, "This is the day when Allah caused Moses and the children of Israel to have victory over Pharaoh, so we fast on this day as a sign of glorifying it." Messenger of Allah ﷺ said, "We are closer to Moses than you." Then he ordered that fasting on this day should be observed.  

لَمَّا قَدِمَ النَّبِيُّ ﷺ الْمَدِينَةَ وَجَدَ الْيَهُودَ يَصُومُونَ عَاشُورَاءَ فَسُئِلُوا عَنْ ذَلِكَ فَقَالُوا هَذَا الْيَوْمُ الَّذِي أَظْفَرَ اللَّهُ فِيهِ مُوسَى وَبَنِي إِسْرَائِيلَ عَلَى فِرْعَوْنَ وَنَحْنُ نَصُومُهُ تَعْظِيمًا لَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ نَحْنُ أَوْلَى بِمُوسَى مِنْكُمْ ثُمَّ أَمَرَ بِصَوْمِهِ  

When Messenger of Allah ﷺ arrived at Medina, he found the Jews observing the fast on the day of 'Ashura' (10th of Muharram). The Prophet ﷺ asked them (about it) and they replied, "This is the day when Moses became victorious over Pharaoh." The Prophet ﷺ said (to the Muslims), "We are nearer to Moses than they, so fast on this day."  

لَمَّا قَدِمَ رَسُولُ اللَّهِ ﷺ الْمَدِينَةَ وَالْيَهُودُ تَصُومُ عَاشُورَاءَ فَسَأَلَهُمْ فَقَالُوا هَذَا الْيَوْمُ الَّذِي ظَهَرَ فِيهِ مُوسَى عَلَى فِرْعَوْنَ فَقَالَ النَّبِيُّ ﷺ نَحْنُ أَوْلَى بِمُوسَى مِنْهُمْ فَصُومُوهُ  

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 ﷺ said: We have more right, and we have a closer connection with Moses than you have; so Messenger of Allah ﷺ observed fast (on the day of 'Ashura), and gave orders that it should be observed.  

أَنَّ رَسُولَ اللَّهِ ﷺ قَدِمَ الْمَدِينَةَ فَوَجَدَ الْيَهُودَ صِيَامًا يَوْمَ عَاشُورَاءَ فَقَالَ لَهُمْ رَسُولُ اللَّهِ ﷺ 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 ﷺ فَنَحْنُ أَحَقُّ وَأَوْلَى بِمُوسَى مِنْكُمْ فَصَامَهُ رَسُولُ اللَّهِ ﷺ وَأَمَرَ بِصِيَامِهِ  

When the Prophet ﷺ came to Medina, he found the Jews observing fast on the day of 'Ashurah; so they were asked about it (by the Prophet). They said: This is a day on which Allah gave Moses domination over Pharaoh. We fast on it out of reverence to him. The Messenger of Allah ﷺ said: We have a closer connection with Moses than you have. He then gave orders that it should be observed.  

لَمَّا قَدِمَ النَّبِيُّ ﷺ الْمَدِينَةَ وَجَدَ الْيَهُودَ يَصُومُونَ عَاشُورَاءَ فَسُئِلُوا عَنْ ذَلِكَ فَقَالُوا هَذَا الْيَوْمُ الَّذِي أَظْهَرَ اللَّهُ فِيهِ مُوسَى عَلَى فِرْعَوْنَ وَنَحْنُ نَصُومُهُ تَعْظِيمًا لَهُ فَقَالَ رَسُولُ اللَّهِ ﷺ نَحْنُ أَوْلَى بِمُوسَى مِنْكُمْ وَأَمَرَ بِصِيَامِهِ

قَدِمَ رَسُولُ اللهِ ﷺ الْمَدِينَةَ فَإِذَا الْيَهُودُ قَدْ صَامُوا يَوْمَ عَاشُورَاءَ فَسَأَلَهُمْ عَنْ ذَلِكَ فَقَالُوا هَذَا الْيَوْمُ الَّذِي ظَهَرَ فِيهِ مُوسَى عَلَى فِرْعَوْنَ فَقَالَ النَّبِيُّ ﷺ لِأَصْحَابِهِ أَنْتُمْ أَوْلَى بِمُوسَى مِنْهُمْ فَصُومُوهُ
