Narrated by Sayyiduna Usama bin Zaid (may Allah be pleased with him), he says: I said, "O Messenger of Allah! If Allah wills, where will you stay in Makkah tomorrow?" This was during the time of the conquest of Makkah. The Prophet (peace and blessings be upon him) said, "Has Aqeel left any place for us?" Then the Prophet (peace and blessings be upon him) said, "A disbeliever cannot inherit from a believer, nor can a believer inherit from a disbeliever."

It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: Those of two different religions will not inherit from each other.

Abu Aswad Daili says that Sayyiduna Mu'adh (may Allah be pleased with him) was in Yemen. People brought to him the case of a Jew who had died and had left behind a Muslim brother as his heir. Sayyiduna Mu'adh (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings be upon him) say that Islam increases, it does not decrease. Then he made that Muslim the heir of the Jew.

It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that a man deliberately killed his son. When his case was presented before Sayyiduna Umar bin Khattab (may Allah be pleased with him), he determined as blood money for the killer thirty hiqqahs, thirty jadh’ahs, and forty two-toothed camels, and said: The killer does not become an heir. Then he said: If I had not heard the Messenger of Allah (peace and blessings be upon him) say that a father should not be killed in retaliation for his child, I would have killed you in retribution.

It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that Sayyiduna Umar (may Allah be pleased with him) said: If I had not heard the Messenger of Allah (peace and blessings be upon him) say that the killer does not inherit anything, I would have made you the heir of the murdered son. Then he called the brother of the murdered person and gave him camels.

It is narrated from Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with them both) that Sayyiduna Umar (may Allah be pleased with him) took thirty hiqqahs, thirty jadh’ahs, and forty such she-camels which were from two-toothed up to entering the ninth year, and all of them were pregnant. Then he called the brother of the murdered man and gave him all these camels, and gave nothing to the father, and said: I heard the Messenger of Allah (peace and blessings of Allah be upon him) say that the killer has no share in inheritance.
