وَعَنِ ابْنِ عَبَّاسٍ قَالَ: كُنَّا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فِي سَفَرٍ فَحَضَرَ الْأَضْحَى فَاشْتَرَكْنَا فِي الْبَقَرَةِ سَبْعَةٌ وَفِي الْبَعِيرِ عَشَرَةٌ. رَوَاهُ التِّرْمِذِيُّ وَالنَّسَائِيُّ وَابْنُ مَاجَهْ وَقَالَ التِّرْمِذِيُّ: هَذَا حَدِيثٌ حَسَنٌ غريبٌ

Ibn ‘Abbas said, "We were with God’s Messenger on a journey when the day of sacrifice came, and we shared with one another, seven for a cow and ten for a camel.” Tirmidhi, Nasa’i and Ibn Majah transmitted it, and Tirmidhi said this is a hasan gharib tradition.
