The Book of Fasting
13/18. Chapter:
It is recommended for the person performing Hajj in 'Arafat not to fast on the day of 'Arafah.
Sahih Muslim
حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، وَابْنُ أَبِي عُمَرَ، عَنْ سُفْيَانَ، عَنْ أَبِي النَّضْرِ، بِهَذَا الإِسْنَادِ . وَلَمْ يَذْكُرْ وَهُوَ وَاقِفٌ عَلَى بَعِيرِهِ . وَقَالَ عَنْ عُمَيْرٍ مَوْلَى أُمِّ الْفَضْلِ .
This hadith has been narrated on the authority of Abu Nadr with the same chain of transmitters, but he did not mention that he was mounting (riding on) his camel.
