Ibn 'Abbas reported:
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، حَدَّثَنَا عَبْدُ الرَّحِيمِ بْنُ سُلَيْمَانَ ، عَنْ عَبْدِ الْمَلِكِ بْنِ أَبِي سُلَيْمَانَ ، عَنْ عَطَاءٍ ، عَنِ ابْنِ عَبَّاسٍ ، أَنَّ النَّبِيَّ صلى الله عليه وسلم مَرَّ بِشَاةٍ لِمَوْلاَةٍ لِمَيْمُونَةَ فَقَالَ " أَلاَّ انْتَفَعْتُمْ بِإِهَابِهَا " .
The Apostle of Allah (ﷺ) happened to pass by (the dead body) of the goat which belonged to the freed slave-girl of Maimuna and said: Why did you not make use of its skin?
