Sunan an-Nasa'i 3009
It was narrated from Salim bin Abdullah that:
Abdullah bin Umar came to Al-Hajjaj bin Yusuf on the day of Arafat when the sun has passed its zenith, and I was with him. He said: "We have to move on if you want to follow Sunnah." He said to him: "At this hours?" He said: Yes." Salim said: "I said to Al-Hajjaj: 'If you want to follow the Sunnah, then deliver a short Khutbah and hasten to pray.' Abdullah bin Umar said: 'He is telling the truth.'"
أَخْبَرَنَا أَحْمَدُ بْنُ عَمْرِو بْنِ السَّرْحِ، قَالَ حَدَّثَنَا ابْنُ وَهْبٍ، أَخْبَرَنِي مَالِكٌ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ، جَاءَ إِلَى الْحَجَّاجِ بْنِ يُوسُفَ يَوْمَ عَرَفَةَ حِينَ زَالَتِ الشَّمْسُ وَأَنَا مَعَهُ، فَقَالَ الرَّوَاحَ إِنْ كُنْتَ تُرِيدُ السُّنَّةَ ‏.‏ فَقَالَ هَذِهِ السَّاعَةَ قَالَ نَعَمْ ‏.‏ قَالَ سَالِمٌ فَقُلْتُ لِلْحَجَّاجِ إِنْ كُنْتَ تُرِيدُ أَنْ تُصِيبَ الْيَوْمَ السُّنَّةَ فَاقْصُرِ الْخُطْبَةَ وَعَجِّلِ الصَّلاَةَ ‏.‏ فَقَالَ عَبْدُ اللَّهِ بْنُ عُمَرَ صَدَقَ ‏.‏
