'Abdullah bin 'Ubaidullah bin 'Abbas said: "We were sitting with 'Abdullah bin 'Abbas and he said: 'By Allah, the Messenger of Allah (ﷺ) did not say specifically anything for us above the people, except for three things: He commanded us to do Wudu' properly, [2] not to consume charity, and not to mate donkeys with horses.'"

أَخْبَرَنَا يَحْيَى بْنُ حَبِيبِ بْنِ عَرَبِيٍّ، قَالَ حَدَّثَنَا حَمَّادٌ، قَالَ حَدَّثَنَا أَبُو جَهْضَمٍ، قَالَ حَدَّثَنِي عَبْدُ اللَّهِ بْنُ عُبَيْدِ اللَّهِ بْنِ عَبَّاسٍ، قَالَ كُنَّا جُلُوسًا إِلَى عَبْدِ اللَّهِ بْنِ عَبَّاسٍ فَقَالَ وَاللَّهِ مَا خَصَّنَا رَسُولُ اللَّهِ صلى الله عليه وسلم بِشَىْءٍ دُونَ النَّاسِ إِلاَّ بِثَلاَثَةِ أَشْيَاءَ فَإِنَّهُ أَمَرَنَا أَنْ نُسْبِغَ الْوُضُوءَ وَلاَ نَأْكُلَ الصَّدَقَةَ وَلاَ نُنْزِيَ الْحُمُرَ عَلَى الْخَيْلِ ‏.‏
