The Prophet (ﷺ) said, " If somebody dies (among the Muslims) leaving some property, the property will go to his heirs; and if he leaves a debt or dependants, we will take care of them."

the Prophet (ﷺ) said, "A Muslim cannot be the heir of a disbeliever, nor can a disbeliever be the heir of a Muslim."

Sa`d bin Abi Waqqas and 'Abu bin Zam`a had a dispute over a boy. Sa`d said, "O Allah's Messenger (ﷺ)! This (boy) is the son of my brother, `Utba bin Abi Waqqas who told me to be his custodian as he was his son. Please notice to whom he bears affinity." And 'Abu bin Zam`a said, "This is my brother, O Allah's Messenger (ﷺ)! He was born on my father's bed by his slave girl." Then the Prophet (ﷺ) looked at the boy and noticed evident resemblance between him and `Utba, so he said, "He (the toy) is for you, O 'Abu bin Zam`a, for the boy is for the owner of the bed, and the stone is for the adulterer. Screen yourself before the boy, O Sauda bint Zam`a." `Aisha added: Since then he had never seen Sauda.

I heard the Prophet (ﷺ) saying, "Whoever claims to be the son of a person other than his father, and he knows that person is not his father, then Paradise will be forbidden for him." I mentioned that to Abu Bakra, and he said, "My ears heard that and my heart memorized it from Allah's Messenger (ﷺ).

The Prophet (ﷺ) said, "Do not deny your fathers (i.e. claim to be the sons of persons other than your fathers), and whoever denies his father, is charged with disbelief."

Allah's Messenger (ﷺ) said, "There were two women with whom there were their two sons. A wolf came and took away the son of one of them. That lady said to her companion, 'The wolf has taken your son.' The other said, 'But it has taken your son.' So both of them sought the judgment of (the Prophet) David who judged that the boy should be given to the older lady. Then both of them went to (the Prophet) Solomon, son of David and informed him of the case. Solomon said, 'Give me a knife so that I may cut the child into two portions and give one half to each of you.' The younger lady said, 'Do not do so; may Allah bless you ! He is her child.' On that, he gave the child to the younger lady." Abu Huraira added: By Allah! I had never heard the word 'Sakkin' as meaning knife, except on that day, for we used to call it "Mudya".

Allah's Messenger (ﷺ) once entered upon me in a very happy mood, with his features glittering with joy, and said, "O `Aisha! won't you see that Mujazziz (a Qa'if) looked just now at Zaid bin Haritha and Usama bin Zaid and said, 'These feet (of Usama and his father) belong to each other." (See Hadith No. 755, Vol. 4)

Once Allah's Messenger (ﷺ) entered upon me and he was in a very happy mood and said, "O `Aisha: Don't you know that Mujazziz Al-Mudliji entered and saw Usama and Zaid with a velvet covering on them and their heads were covered while their feet were uncovered. He said, 'These feet belong to each other.'
