Fatimah sent word to Abu Bakr asking for her inheritance from the Prophet, from his charity and what was left of the Khumus of Khaibar. Abu Bakar said: "The Messenger of Allah said: 'We are not inherited from."' (Using translation from Nasāʾī 4141)
أَنَّ فَاطِمَةَ أَرْسَلَتْ إِلَى أَبِي بَكْرٍ تَسْأَلُهُ مِيرَاثَهَا مِنَ النَّبِيِّ ﷺ مِنْ صَدَقَتِهِ وَمِمَّا تَرَكَ وَمِنْ خُمُسِ خَيْبَرَ فَقَالَ أَبُو بَكْرٍ إِنَّ رَسُولَ اللهِ ﷺ قَالَ «لَا نُورَثُ مَا تَرَكْنَا صَدَقَةٌ»
