Hisham bin Urwah narrates from his father that Sayyiduna Zubair (may Allah be pleased with him) stated that this verse was revealed about us: "And blood relatives are heirs of one another (this is the command in Allah's Book)." The Prophet (peace and blessings be upon him) made two Muhajir and one Ansari brothers to each other, so we had no doubt that we would inherit from one another, meaning if Sayyiduna Ka'b (may Allah be pleased with him) passed away and had no heir, I thought that I would become his heir, and if I died, then likewise he would become my heir, until this verse was revealed.

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) was asked about the inheritance of the paternal and maternal aunts. He replied: "I do not have knowledge about this; Jibreel (peace be upon him) will come and inform me about it." Then he said: "Where is the person who asked about the inheritance of the paternal and maternal aunts?" That person was brought, and the Prophet said: "Jibreel (peace be upon him) has informed me that neither of them will receive anything (i.e., they will not inherit)." This narration has only been transmitted by a narrator named Mas'adah from Muhammad bin Amr, and this narrator is weak. The correct view is that this narration is "mursal."

This narration is also transmitted from the Prophet Muhammad (peace be upon him) with another chain of transmission.

Sha'bi narrates: Ziyad bin Abu Sufyan said to his companion: "Do you know what decision Sayyiduna Umar (may Allah be pleased with him) gave regarding the paternal and maternal aunts?" The person replied: "No, I do not!" So Ziyad said: "I know best what Sayyiduna Umar (may Allah be pleased with him) decided about this; he placed the maternal aunt in the position of the mother and the paternal aunt in the position of the father."
