عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا قَالَ: أَخْبَرَنِي الْفَضْلُ بْنُ عَبَّاسٍ وَكَانَ رَدِيفَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ حِينَ أَفَاضَ مِنْ عَرَفَةَ قَالَ: فَرَأَى النَّاسَ يُوْضِعُونَ فَأَمَرَ مُنَادِيَهُ فَنَادَى: لَيْسَ الْبِرُّ بِإِيضَاعِ الْخَيْلِ وَالْإِبِلِ فَعَلَيْكُمْ بِالسَّكِينَةِ
It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with him), he says: Sayyiduna Fadl bin Abbas (may Allah be pleased with him) informed me, while he was riding behind the Messenger of Allah (peace and blessings be upon him) on his mount on the return from Arafah. When the Messenger of Allah (peace and blessings be upon him) saw that people were urging their mounts to run fast, he (peace and blessings be upon him) ordered a caller to announce: Racing horses and camels is not righteousness; proceed calmly.
