Al-Adab Al-Mufrad, Book 55, Hadith 1298 (In-Book)

Abu 'Uqba said, "I once walked along the road with Ibn 'Umar. I passed some Abyssinian lads who were playing and he brought out two dirhams which he gave to them."

حَدَّثَنَا مُوسَى، قَالَ‏:‏ حَدَّثَنَا عَبْدُ الْعَزِيزِ قَالَ‏:‏ حَدَّثَنِي شَيْخٌ مِنْ أَهْلِ الْخَيْرِ يُكَنَّى أَبَا عُقْبَةَ قَالَ‏:‏ مَرَرْتُ مَعَ ابْنِ عُمَرَ مَرَّةً بِالطَّرِيقِ، فَمَرَّ بِغِلْمَةٍ مِنَ الْحَبَشِ، فَرَآهُمْ يَلْعَبُونَ، فَأَخْرَجَ دِرْهَمَيْنِ فَأَعْطَاهُمْ‏.‏
