It is narrated from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "A Muslim does not inherit from a Christian, unless he is his slave or slave woman." This narrator, Muhammad bin Amr, is al-Yafi'i of Egypt, who is saduq (truthful) and sahih in hadith, and the basis of this hadith is the narration of Amr bin Shu'ayb (which follows).

It is narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "A Muslim does not inherit from a disbeliever, nor does a disbeliever inherit from a Muslim."

Ja'far bin Muhammad narrates from his father that Sayyidah Umm Kulthum bint Ali (may Allah be pleased with them both) and her son Zayd bin Umar bin al-Khattab died on the same day, and it could not be known which of them died first; so she did not inherit from him, nor did he inherit from her. Likewise, the martyrs of the Battle of Siffin and of the Event of al-Harrah did not inherit from one another. The chain of this hadith is sahih (authentic). It contains points of benefit, one of which is that Sayyidah Umm Kulthum (may Allah be pleased with her) bore Sayyiduna Umar (may Allah be pleased with him) a son; and for the other point of benefit there is a supporting narration:

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that he would not make one deceased person the heir of another deceased person when it was not known which of them died before the other.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) concerning the saying of Allah Almighty: "And those with whom you have made pledges, give them their share" [Surah al-Nisa: 33] , that he said: (Previously) a man would make a pact with another man, even though there was no blood relationship between them, so that each could inherit from the other; then Allah Almighty abrogated this through this verse of Surah al-Anfal: "And blood relatives are more entitled to one another in the Book of Allah" [Surah al-Anfal: 75] .

It is narrated from Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) that he said on the pulpit (while delivering a sermon) that he had distributed the inheritance of a man who left a daughter and a sister, and he fixed half for the daughter and (the remaining) half for the sister, while the Messenger of Allah (peace and blessings be upon him) was alive among them at that time. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that a man died, and the Prophet (peace and blessings be upon him) said: "Look for an heir of his." But no heir was found except a freed slave (mawla) of his, so the Messenger of Allah (peace and blessings be upon him) said: "Give the inheritance to him." This hadith is sahih (authentic) on the condition of Imam Bukhari, but the two Shaykhs (Bukhari and Muslim) did not record it. However, Hammad bin Salamah and Sufyan bin Uyaynah narrated it from Amr bin Dinar, from Awsajah the freed slave of Ibn Abbas, from Ibn Abbas.

According to the narration of Hammad bin Salamah, it is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that in the blessed time of the Messenger of Allah (peace and blessings be upon him), a man died and left no heir or close relative except the slave he had freed, so the Prophet (peace and blessings be upon him) gave the inheritance to that slave.

Awsajah (the freed slave of Ibn Abbas) narrates: I heard Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) say that in the blessed time of the Messenger of Allah (peace and blessings be upon him), a man died who left no heir or relative except the slave he had freed, so the Prophet (peace and blessings be upon him) gave his inheritance (to that slave).

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that people brought before Sayyiduna Ali (may Allah be pleased with him) the case of the child of a woman who underwent li'an. The 'asabah (relatives) of his father came demanding his inheritance, whereupon Sayyiduna Ali (may Allah be pleased with him) said: Indeed, his father had disowned him (through li'an). So he gave his inheritance to his mother, made her his 'asabah, and gave those people nothing. This hadith has a sahih (authentic) chain of narration; although it is mawquf as a ruling of the Commander of the Faithful, it is a rare narration among his fatwas and rulings.
