"I saw the Messenger of Allah when people came to him and asked him about Hajj. The Messenger of Allah said: 'Hajj is Arafat. Whoever catches up with the night of Arafat before dawn comes on the night of Jam (Al-Muzdalifah), his Hajj is complete.'" (Using translation from Nasāʾī 3016)   

شَهِدْتُ رَسُولَ اللهِ ﷺ بِعَرَفَةَ وَأَتَاهُ نَاسٌ مِنْ أَهْلِ نَجْدٍ فَسَأَلُوهُ عَنِ الْحَجِّ فَقَالَ رَسُولُ اللهِ ﷺ «الْحَجُّ عَرَفَةُ فَمَنْ أَدْرَكَ لَيْلَةَ عَرَفَةَ قَبْلَ طُلُوعِ الْفَجْرِ مِنْ لَيْلَةِ جَمْعٍ فَقَدْ تَمَّ حَجَّهُ»  

[Machine] I heard the Messenger of Allah ﷺ say, "Hajj is Arafat." He repeated it three times. "So whoever reaches Arafat before dawn breaks has indeed reached the days of Mina for three days. And whoever hastens in two days, there is no sin upon him. And whoever delays, there is no sin upon him."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «الْحَجُّ عَرَفَاتٌ» ثَلَاثًا «فَمَنْ أَدْرَكَ عَرَفَةَ قَبْلَ أَنْ يَطْلُعَ الْفَجْرُ فَقَدْ أَدْرَكَ أَيَّامُ مِنًى ثَلَاثٌ فَمَنْ تَعَجَّلَ فِي يَوْمَيْنِ فَلَا إِثْمَ عَلَيْهِ وَمَنْ تَأَخَّرَ فَلَا إِثْمَ عَلَيْهِ»  

"The Quraish used to stand in Al-Muzdalifah and they called themselves Al-Hums, and the rest of Arabs stood in Arafat. Then Allah, Blessed and Most High, commanded his Prophet to stand in Arafat, and then move on from there. Allah, the Mighty and Sublime, revealed: 'Then depart from the place whence all the people depart.'" (Using translation from Nasāʾī 3012)   

كَانَتْ قُرَيْشٌ تَقِفُ بِالْمُزْدَلِفَةِ وَيُسَمَّوْنَ الْحُمْسَ وَسَائِرُ الْعَرَبِ تَقْفُ بِعَرَفَةَ فَأَمَرَ اللهُ نَبِيَّهُ ﷺ أَنْ يَقِفَ بِعَرَفَةَ ثُمَّ يَرْفَعَ مِنْهَا فَأَنْزَلَ اللهُ {ثُمَّ أَفِيضُوا مِنْ حَيْثُ أَفَاضَ النَّاسُ} [البقرة 199]  

"The Messneger of Allah departed from Arafat and I was riding behind him. He started trying to rein in his camel until its ears nearly touched the front of the saddle, and he was saying: 'O people, you must be tranquil and dignified, for righteousness does not come by making camels hurry.'" (Using translation from Nasāʾī 3018)  

أَفَاضَ رَسُولُ اللهِ ﷺ مِنْ عَرَفَةَ وَأنا رَدِيفُهُ فَجَعَلَ يَكْبَحُ رَاحِلَتَهُ حَتَّى إِنَّ ذَفْرَاهَا لَتَكَادُ تُصِيبُ قَادِمَةَ الرَّحْلِ وَهُوَ يَقُولُ «يَا أَيُّهَا الَّذِينَ آمَنُوا عَلَيْكُمْ بِالسَّكِينَةِ وَالْوَقَارِ فَإِنَّ الْبِرَّ لَيْسَ فِي إِيضَاعِ الْإِبِلِ»
