“Allah and His Messenger are the guardians of the one who has no guardian, and the maternal uncle is the heir of one who has no other heir.”
Sunan Ibn Majah Book 23, Hadith 19
← Previous Hadith “A woman inherits from the blood money and wealth of her husband, and he inherits from her blood money and wealth, so long as one of them did not kill the other. If one of them killed the other deliberately, then he or she inherits nothing from the blood money or wealth. If one of them killed the other by mistake, he or she inherits from the other’s wealth, but not from the blood money.”

Sunan Ibn Majah Book 23, Hadith 18 Next Hadith → “Whoever leaves behind wealth, it is for his heirs. Whoever leaves behind poor dependents and a debt, it is for us to take care of – or he said: ‘It is for Allah and His Messenger (to take care of) – I am the heir of the one who has no heir, I will pay the blood money on his behalf and inherit from him. And the maternal uncle is the heir of the one who has no heir, he pays blood money on his behalf and inherits from him.”
