From Sahih Bukhari (Hadith 6730):
Narrated `Urwa:`Aisha said, "When Allah's Messenger (ﷺ) died, his wives intended to send `Uthman to Abu Bakr asking him for their share of the inheritance." Then `Aisha said to them, "Didn't Allah's Messenger (ﷺ) say, 'Our (Apostles') property is not to be inherited, and whatever we leave is to be spent in charity?
