When the Messenger of Allah ﷺ died, the wives of the Prophet ﷺ intended to send 'Uthman b. 'Affan to Abu Bakr to ask him their cost of living from (the inheritance of) the Prophet ﷺ. Thereupon 'Aishah said: Did not the Messenger of Allah ﷺ say: We are not inherited. Whatever we leave is sadaqah. (Using translation from Abū Dāʾūd 2976)
أَنَّ أَزْوَاجَ النَّبِيِّ ﷺ حِينَ تُوُفِّيَ رَسُولُ اللهِ ﷺ أَرَدْنَ أَنْ يُرْسِلْنَ عُثْمَانَ إِلَى أَبِي بَكْرٍ يَسْأَلْنَهُ مِيرَاثَهُنَّ مِنْ رَسُولِ اللهِ ﷺ فَقَالَتْ لَهُنَّ عَائِشَةُ أَوَلَيْسَ قَدْ قَالَ رَسُولُ اللهِ ﷺ لَا نُورَثُ مَا تَرَكْنا فَهُوَ صَدَقَةٌ
