Once a Jew said to me, "O the chief of believers! There is a verse in your Holy Book Which is read by all of you (Muslims), and had it been revealed to us, we would have taken that day (on which it was revealed as a day of celebration." 'Umar bin Al-Khattab asked, "Which is that verse?" The Jew replied, "This day I have perfected your religion For you, completed My favor upon you, And have chosen for you Islam as your religion." (5:3) 'Umar replied,"No doubt, we know when and where this verse was revealed to the Prophet. It was Friday and the Prophet ﷺ was standing at 'Arafat (i.e. the Day of Hajj)"  

لَهُ يَا أَمِيرَ الْمُؤْمِنِينَ آيَةٌ فِي كِتَابِكُمْ تَقْرَءُونَهَا لَوْ عَلَيْنَا مَعْشَرَ الْيَهُودِ نَزَلَتْ لاَتَّخَذْنَا ذَلِكَ الْيَوْمَ عِيدًا قَالَ أَىُّ آيَةٍ قَالَ {الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي وَرَضِيتُ لَكُمُ الإِسْلاَمَ دِينًا} قَالَ عُمَرُ قَدْ عَرَفْنَا ذَلِكَ الْيَوْمَ وَالْمَكَانَ الَّذِي نَزَلَتْ فِيهِ عَلَى النَّبِيِّ ﷺ وَهُوَ قَائِمٌ بِعَرَفَةَ يَوْمَ جُمُعَةٍ  

If this verse were revealed in relation to the Jews (i e. "This day I have perfected your religion for you and have completed My favours for you and have chosen for you al-Islam as religion") we would have taken the day of rejoicing on which this verse was revealed. Thereupon 'Umar said: I know the day on which it was revealed and the hour when it was revealed and where Messenger of Allah ﷺ had been when it was revealed. It was revealed on the night of Friday and we were in 'Arafat with Messenger of Allah ﷺ at that time.  

قَالَتِ الْيَهُودُ لِعُمَرَ لَوْ عَلَيْنَا مَعْشَرَ يَهُودَ نَزَلَتْ هَذِهِ الآيَةُ { الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي وَرَضِيتُ لَكُمُ الإِسْلاَمَ دِينًا} نَعْلَمُ الْيَوْمَ الَّذِي أُنْزِلَتْ فِيهِ لاَتَّخَذْنَا ذَلِكَ الْيَوْمَ عِيدًا قَالَ فَقَالَ عُمَرُ فَقَدْ عَلِمْتُ الْيَوْمَ الَّذِي أُنْزِلَتْ فِيهِ وَالسَّاعَةَ وَأَيْنَ رَسُولُ اللَّهِ ﷺ حِينَ نَزَلَتْ نَزَلَتْ لَيْلَةَ جَمْعٍ وَنَحْنُ مَعَ رَسُولِ اللَّهِ ﷺ بِعَرَفَاتٍ  

Commander of the Faithful, there is a verse in your Book, which you recite. Had it been revealed in connection with the Jews, we would have taken it as the day of rejoicing. Thereupon he said: Which verse do you mean? He replied:" This day I have perfected your religion for you and I have completed My favours upon you and I have chosen al-Islam as religion for you." Umar said, I know the day when it was revealed and the place where it was revealed. It was revealed to Messenger of Allah ﷺ at 'Arafat on Friday.  

جَاءَ رَجُلٌ مِنَ الْيَهُودِ إِلَى عُمَرَ فَقَالَ يَا أَمِيرَ الْمُؤْمِنِينَ آيَةٌ فِي كِتَابِكُمْ تَقْرَءُونَهَا لَوْ عَلَيْنَا نَزَلَتْ مَعْشَرَ الْيَهُودِ لاَتَّخَذْنَا ذَلِكَ الْيَوْمَ عِيدًا قَالَ وَأَىُّ آيَةٍ قَالَ { الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي وَرَضِيتُ لَكُمُ الإِسْلاَمَ دِينًا} فَقَالَ عُمَرُ إِنِّي لأَعْلَمُ الْيَوْمَ الَّذِي نَزَلَتْ فِيهِ وَالْمَكَانَ الَّذِي نَزَلَتْ فِيهِ نَزَلَتْ عَلَى رَسُولِ اللَّهِ ﷺ بِعَرَفَاتٍ فِي يَوْمِ جُمُعَةٍ  

"A Jewish man came to 'Umar bin Al-Khattab and said: 'O Commander of the Believers! There is a Verse in your Book which you recite; if it had been revealed to us Jews we would have taken that day as a festival.' He said: 'Which Verse is that?' He said: 'This day, I have perfected your religion for you, completed My favor upon you, and have chosen for you Islam as your religion.' 'Umar said: 'I know the place where it was revealed and the day on which it was revealed. It was revealed to the Messenger of Allah [SAW] at 'Arafat, on a Friday.'"  

يَا أَمِيرَ الْمُؤْمِنِينَ آيَةٌ فِي كِتَابِكُمْ تَقْرَءُونَهَا لَوْ عَلَيْنَا مَعْشَرَ الْيَهُودِ نَزَلَتْ لَاتَّخَذْنَا ذَلِكَ الْيَوْمَ عِيدًا قَالَ أَيُّ آيَةٍ قَالَ الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي وَرَضِيتُ لَكُمْ الْإِسْلَامَ دِينًا فَقَالَ عُمَرُ إِنِّي لَأَعْلَمُ الْمَكَانَ الَّذِي نَزَلَتْ فِيهِ وَالْيَوْمَ الَّذِي نَزَلَتْ فِيهِ نَزَلَتْ عَلَى رَسُولِ اللَّهِ ﷺ فِي عَرَفَاتٍ فِي يَوْمِ جُمُعَةٍ  

A Jewish man came to 'Umar and said: O Ameer al-Mu'mineen, you read a verse in your Book which, if it had been revealed to us Jews, we would have taken that day as a festival. He said: Which verse is it? He said: The verse: ʿThis day, I have perfected your religion for you, completed My Favour upon you” (al Ma'idah 5:3]. 'Umar said: By Allah, I know the day on which this was revealed to the Messenger of Allah ﷺ and the hour at which it was revealed to the Messenger of Allah ﷺ, on the afternoon of 'Arafah on a Friday.  

يَا أَمِيرَ الْمُؤْمِنِينَ إِنَّكُمْ تَقْرَءُونَ آيَةً فِي كِتَابِكُمْ لَوْ عَلَيْنَا مَعْشَرَ الْيَهُودِ نَزَلَتْ لاتَّخَذْنَا ذَلِكَ الْيَوْمَ عِيدًا قَالَ وَأَيُّ آيَةٍ هِيَ؟ قَالَ قَوْلُهُ ﷻ {الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي} [المائدة 3] قَالَ فَقَالَ عُمَرُ وَاللهِ إِنَّي لَأَعْلَمُ الْيَوْمَ الَّذِي نَزَلَتْ عَلَى رَسُولِ اللهِ ﷺ وَالسَّاعَةَ الَّتِي نَزَلَتْ فِيهَا عَلَى رَسُولِ اللهِ ﷺ عَشِيَّةَ عَرَفَةَ فِي يَوْمِ الْجُمُعَةِ  

[Machine] "O Amir al-Mu'minin, there is a verse in your book that you recite. If it had been revealed upon us, the Jewish people, we would have taken that day as a celebration." He asked, "Which verse is it?" I said, "The verse is: 'This day I have perfected for you your religion and completed My favor upon you and have approved for you Islam as religion' [Surah Al-Ma'idah, verse 3]." Umar said, "We know the day and the place where it was revealed. It was revealed to the Messenger of Allah ﷺ on the day of Arafah, which was a Friday."  

لِعُمَرَ ؓ يَا أَمِيرَ الْمُؤْمِنِينَ آيَةٌ فِي كِتَابِكُمْ تَقْرَأُونَهَا لَوْ عَلَيْنَا مَعْشَرَ الْيَهُودِ نَزَلَتْ لَاتَّخَذْنَا ذَلِكَ الْيَوْمَ عِيدًا فَقَالَ أِيُّ آيَةٍ؟ قَالَ {الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي وَرَضِيتُ لَكُمُ الْإِسْلَامَ دِينًا} [المائدة 3] فَقَالَ عُمَرُ ؓ فَقَدْ عَرَفْنَا ذَلِكَ الْيَوْمَ وَالْمَكَانَ الَّذِي أُنْزِلَتْ فِيهِ نَزَلَتْ عَلَى رَسُولِ اللهِ ﷺ بِعَرَفَاتٍ يَوْمَ جُمُعَةٍ  

"عن طارق بن شهابٍ قال: جاء رجل من اليهودِ إلي عمر فقال: يا أميرَ المؤمنين إنكم تقرأُون آية في كتابِكم لو علينا معشرَ اليهود نزلت لاتخذنا ذلكَ اليوم عيدًا، قال: أيُّ آية هي؟ قال: قوله: {الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي} قال عمر: والله إني لأعلم (اليوم) (*) الذي نزلت على رسول الله ﷺ : والساعة التي نزلت على رسول الله ﷺ عَشِية عرفة، يوم الجمعة".
