Say (O Muhammad, unto mankind): I warn you only by the Inspiration. But the deaf hear not the call when they are warned.

Sahih al-Bukhari
Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
Chapter: The story of Bani An-Nadir
Narrated `Aisha:
Fatima and Al-`Abbas came to Abu Bakr, claiming their inheritance of the Prophet's land of Fadak and his share from Khaibar. Abu Bakr said, "I heard the Prophet (ﷺ) saying, 'Our property is not inherited, and whatever we leave is to be given in charity. But the family of Muhammad can take their sustenance from this property.' By Allah, I would love to do good to the Kith and kin of Allah's Apostle rather than to my own Kith and kin."
Sahih al-Bukhari 4035, 4036
