that the Messenger of Allah ﷺ said: "The Hajj is 'Arafat, the Hajj is 'Arafat, the Hajj is 'Arafat. The days of Mina are three: But whoever hastens to leave in two days, there is no sin on him, and whoever stays on, there is no sin on him (2:203). And whoever sees (attends) the 'Arafah before the rising of Fajr, then he has performed the Hajj." Ibn Abi 'Umar said: "Sufyan bin 'Uyainah said: 'This is the best Hadith that Ath-Thawri reported.'"
قَالَ رَسُولُ اللَّهِ ﷺ الْحَجُّ عَرَفَاتٌ الْحَجُّ عَرَفَاتٌ الْحَجُّ عَرَفَاتٌ أَيَّامُ مِنًى ثَلاَثٌ (فَمَنْ تَعَجَّلَ فِي يَوْمَيْنِ فَلاَ إِثْمَ عَلَيْهِ وَمَنْ تَأَخَّرَ فَلاَ إِثْمَ عَلَيْهِ ) وَمَنْ أَدْرَكَ عَرَفَةَ قَبْلَ أَنْ يَطْلُعَ الْفَجْرُ فَقَدْ أَدْرَكَ الْحَجَّ قَالَ ابْنُ أَبِي عُمَرَ قَالَ سُفْيَانُ بْنُ عُيَيْنَةَ وَهَذَا أَجْوَدُ حَدِيثٍ رَوَاهُ الثَّوْرِيُّ
