'Aishah, mother of believers (ra), intended to buy a slave-girl to set her free. Her people said: We shall sell her to you on one condition that we shall inherit from her. 'Aishah mentioned it to the Messenger of Allah ﷺ. He said: That should not prevent you, for the right of inheritance belongs to the one who has set a person free. (Using translation from Abū Dāʾūd 2915)   

أَنَّ عَائِشَةَ زَوْجَ النَّبِيِّ ﷺ أَرَادَتْ أَنْ تَشْتَرِيَ وَلِيدَةً فَتُعْتِقَهَا فَقَالَ أَهْلُهَا نَبِيعُكِهَا عَلَى أَنَّ وَلَاءَهَا لَنَا فَذَكَرَتْ ذَلِكَ لِرَسُولِ اللهِ ﷺ فَقَالَ لَا يَمْنَعْكِ ذَلِكَ فَإِنَّمَا الْوَلَاءُ لِمَنْ أَعْتَقَ أَخْرَجَاهُ فِي الصَّحِيحِ مِنْ حَدِيثِ مَالِكٍ  

[Machine] The foundling belongs to the Muslims; his inheritance is for them, and his guardianship is on them. The owner has nothing of it except the reward.  

اللَّقِيطُ لِلْمُسْلِمِينَ مِيرَاثُهُ وَعَلَيْهِمْ جَرِيرَتُهُ وَلَيْسَ لِصَاحِبِهِ مِنْهُ شَيْءٌ إِلَّا الْأَجْرُ
