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. (Using translation from Muslim 3017c)   

جَاءَ رَجُلٌ مِنَ الْيَهُودِ إِلَى عُمَرَ ؓ فَقَالَ يَا أَمِيرَ الْمُؤْمِنِينَ آيَةٌ فِي كِتَابِكُمْ تَقْرَءُونَهَا لَوْ عَلَيْنَا مَعْشَرَ الْيَهُودِ نَزَلَتْ لَاتَّخَذْنَا ذَلِكَ الْيَوْمَ عِيدًا قَالَ وَأِيُّ آيَةٍ؟ قَالَ {الْيَوْمَ أَكْمَلْتُ لَكُمْ دِينَكُمْ وَأَتْمَمْتُ عَلَيْكُمْ نِعْمَتِي وَرَضِيتُ لَكُمُ الْإِسْلَامَ دِينًا} [المائدة 3] فَقَالَ عُمَرُ ؓ إِنِّي لَأَعْلَمُ الْيَوْمَ الَّذِي نَزَلَتْ فِيهِ وَالْمَكَانَ الَّذِي نَزَلَتْ فِيهِ نَزَلَتْ عَلَى رَسُولِ اللهِ ﷺ بِعَرَفَاتٍ فِي يَوْمِ جُمُعَةٍ  

[Machine] Related to Jabir, he mentioned the long narration about the Hajj, then Bilal called the Adhan, and then the Prophet ﷺ stood up and performed the Dhuhr prayer, then he performed the Asr prayer, without praying anything between them.  

عَنْ جَابِرٍ فَذَكَرَ الْحَدِيثَ الطَّوِيلَ فِي الْحَجِّ وَفِيهِ ثُمَّ أَذَّنَ بِلَالٌ ثُمَّ أَقَامَ فَصَلَّى يَعْنِي رَسُولَ اللهِ ﷺ الظُّهْرَ ثُمَّ أَقَامَ فَصَلَّى الْعَصْرَ لَمْ يُصَلِّ بَيْنَهُمَا شَيْئًا
