Sunan an-Nasa'i 3005
It was narrated that Salim Bin Abdullah said:
"Abdul Malik bin Marwan wrote to Al-Hajjaj bin Yusuf telling him not to go against Ibn Umar with regard to the Hajj. On the day of Arafat, Ibn Umar came to him when the sun had passed its zenith, and I was with him, and shouted near his cotton tent: 'Where is he?' Al-Hajjaj came out to him, wearing a wrap dyed with safflower. He said: 'What is the matter, O Abu Abdur Rahman?' He said: 'We have to move on if you want to follow Sunnah.' He said to him: 'At this hour?' He said: 'Yes.' He said: 'I will pour some water over my self (have a bath) then I will come out to you.' So he waited until he came, then he walked between my father and me, I said: 'If you want to follow the Sunnah, then deliver a short Khutbah and hasten to stand (in Arafat).' He started to look at Ibn Umar so that he could hear that, and when Ibn Umar noticed that he said: 'He is speaking the truth.'"
أَخْبَرَنَا يُونُسُ بْنُ عَبْدِ الأَعْلَى، قَالَ أَخْبَرَنِي أَشْهَبُ، قَالَ أَخْبَرَنِي مَالِكٌ، أَنَّ ابْنَ شِهَابٍ، حَدَّثَهُ عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، قَالَ كَتَبَ عَبْدُ الْمَلِكِ بْنُ مَرْوَانَ إِلَى الْحَجَّاجِ بْنِ يُوسُفَ يَأْمُرُهُ أَنْ لاَ، يُخَالِفَ ابْنَ عُمَرَ فِي أَمْرِ الْحَجِّ فَلَمَّا كَانَ يَوْمُ عَرَفَةَ جَاءَهُ ابْنُ عُمَرَ حِينَ زَالَتِ الشَّمْسُ وَأَنَا مَعَهُ فَصَاحَ عِنْدَ سُرَادِقِهِ أَيْنَ هَذَا فَخَرَجَ إِلَيْهِ الْحَجَّاجُ وَعَلَيْهِ مِلْحَفَةٌ مُعَصْفَرَةٌ فَقَالَ لَهُ مَا لَكَ يَا أَبَا عَبْدِ الرَّحْمَنِ قَالَ الرَّوَاحَ إِنْ كُنْتَ تُرِيدُ السُّنَّةَ ‏.‏ فَقَالَ لَهُ هَذِهِ السَّاعَةَ فَقَالَ لَهُ نَعَمْ ‏.‏ فَقَالَ أُفِيضُ عَلَىَّ مَاءً ثُمَّ أَخْرُجُ إِلَيْكَ ‏.‏ فَانْتَظَرَهُ حَتَّى خَرَجَ فَسَارَ بَيْنِي وَبَيْنَ أَبِي فَقُلْتُ إِنْ كُنْتَ تُرِيدُ أَنْ تُصِيبَ السُّنَّةَ فَاقْصُرِ الْخُطْبَةَ وَعَجِّلِ الْوُقُوفَ ‏.‏ فَجَعَلَ يَنْظُرُ إِلَى ابْنِ عُمَرَ كَيْمَا يَسْمَعَ ذَلِكَ مِنْهُ فَلَمَّا رَأَى ذَلِكَ ابْنُ عُمَرَ قَالَ صَدَقَ ‏.‏
