[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  

[Machine] Umar ibn Al-Khattab, I knew the place where it was revealed, and the day and hour when it was revealed, on the Prophet Muhammad ﷺ while we were in Arafat on the evening of Friday.  

عُمَرُ بْنُ الْخَطَّابِ ؓ قَدْ عَلِمْتُ الْمَوْضِعَ الَّذِي نَزَلَتْ فِيهِ وَالْيَوْمَ وَالسَّاعَةَ نَزَلَتْ عَلَى رَسُولِ اللهِ ﷺ وَنَحْنُ بِعَرَفَةَ عَشِيَّةَ جُمُعَةٍ  

There is no day when God sets free more servants from Hell than the Day of 'Arafa. He draws near, then praises them to the angels, saying: What do these want? (Using translation from Muslim 1348)   

عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّ رَسُولَ اللهِ ﷺ قَالَ مَا مِنْ يَوْمٍ أَكْثَرَ أَنْ يُعْتِقَ اللهُ فِيهِ عَبْدًا مِنَ النَّارِ مِنْ يَوْمِ عَرَفَةَ وَإِنَّهُ لَيَدْنُو ثُمَّ يُبَاهِي الْمَلَائِكَةَ فَيَقُولُ مَا أَرَادَ هَؤُلَاءِ؟  

[Machine] The Messenger of Allah ﷺ prayed on the eve of Arafat to his Ummah for forgiveness and mercy. He supplicated abundantly, and Allah the Almighty revealed to him, "I have forgiven them all except for the wrongs they commit against each other. As for their sins between Me and them, I have forgiven them." The Prophet ﷺ then said, "O Lord, You are able to reward this oppressed one better than his oppression, and You are able to forgive this oppressor." However, he did not receive an answer that evening. When it was the morning of Muzdalifah, he repeated his prayer, and Allah answered him, saying, "I have forgiven them." The Messenger of Allah ﷺ smiled, and when some of his companions asked him about it, he said, "I smiled at the enemy of Allah, Iblis, for when he learned that Allah had answered my prayer for my Ummah, he sank into despair and began calling for woe and destruction upon himself, and he threw dust on his head."  

أَنَّ رَسُولَ اللهِ ﷺ دَعَا عَشِيَّةَ عَرَفَةَ لِأُمَّتِهِ بِالْمَغْفِرَةِ وَالرَّحْمَةِ فَأَكْثَرَ الدُّعَاءَ فَأَوْحَى اللهُ تَعَالَى إِلَيْهِ أَنِّي قَدْ فَعَلْتُ إِلَّا ظُلْمَ بَعْضِهِمْ بَعْضًا وَأَمَّا ذُنُوبُهُمْ فِيمَا بَيْنِي وَبَيْنَهُمْ فَقَدْ غَفَرْتُهَا فَقَالَ يَا رَبِّ إِنَّكَ قَادِرٌ عَلَى أَنْ تُثِيبَ هَذَا الْمَظْلُومَ خَيْرًا مِنْ مَظْلَمَتِهِ وَتَغْفِرَ لِهَذَا الظَّالِمِ فَلَمْ يُجِبْهُ تِلْكَ الْعَشِيَّةَ فَلَمَّا كَانَ غَدَاةَ الْمُزْدَلِفَةِ أَعَادَ الدُّعَاءَ فَأَجَابَهُ اللهُ ﷻ أَنِّي قَدْ غَفَرْتُ لَهُمْ فَتَبَسَّمَ رَسُولُ اللهِ ﷺ فَقَالَ لَهُ بَعْضُ أَصْحَابِهِ يَا رَسُولَ اللهِ تَبَسَّمْتَ فِي سَاعَةٍ لَمْ تَكُنْ تَبَسَّمُ فِيهَا قَالَ تَبَسَّمْتُ مِنْ عَدُوِّ اللهِ إِبْلِيسَ إِنَّهُ لَمَّا عَلِمَ أَنَّ اللهَ قَدِ اسْتَجَابَ لِي فِي أُمَّتِي أَهْوَى يَدْعُو بِالْوَيْلِ وَالثُّبُورِ وَيَحْثُو التُّرَابَ عَلَى رَأْسِهِ
