Sufyan bin Bukair bin ‘Ata’ said:
“I heard ‘Abdur-Rahman bin Ya’mur Dili say: ‘I saw the Messenger of Allah (ﷺ) when he was standing at ‘Arafat, and some people from Najd came to him and said: “O Messenger of Allah, what is Hajj?” He said: “Hajj is ‘Arafah. Whoever comes before Fajr prayer on the night of Jam’, he has completed his Hajj. The days at Mina are three. ‘But whosoever hastens to leave in two days, there is no sin on him and whosoever stays on, there is no sin on him.’” [2:203] Then he seated a man behind him on his mount and he started calling out these words.’”
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَلِيُّ بْنُ مُحَمَّدٍ، قَالاَ حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا سُفْيَانُ، عَنْ بُكَيْرِ بْنِ عَطَاءٍ، سَمِعْتُ عَبْدَ الرَّحْمَنِ بْنَ يَعْمُرَ الدِّيلِيَّ، قَالَ شَهِدْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ وَهُوَ وَاقِفٌ بِعَرَفَةَ وَأَتَاهُ نَاسٌ مِنْ أَهْلِ نَجْدٍ فَقَالُوا يَا رَسُولَ اللَّهِ كَيْفَ الْحَجُّ قَالَ ‏ "‏ الْحَجُّ عَرَفَةُ فَمَنْ جَاءَ قَبْلَ صَلاَةِ الْفَجْرِ لَيْلَةَ جَمْعٍ فَقَدْ تَمَّ حَجُّهُ أَيَّامُ مِنًى ثَلاَثَةٌ فَمَنْ تَعَجَّلَ فِي يَوْمَيْنِ فَلاَ إِثْمَ عَلَيْهِ وَمَنْ تَأَخَّرَ فَلاَ إِثْمَ عَلَيْهِ ‏"‏ ‏.‏ ثُمَّ أَرْدَفَ رَجُلاً خَلْفَهُ فَجَعَلَ يُنَادِي بِهِنَّ ‏.‏
