Musannaf Ibn Abi Shaybah

Hazrat Abu Umamah bin Sahl bin Hunaif (may Allah be pleased with him) narrates that a man shot another man with an arrow, causing his death, and the deceased had no heir except a maternal uncle. Regarding this, Hazrat Abu Ubaidah bin Jarrah (may Allah be pleased with him) wrote a letter to Hazrat Umar (may Allah be pleased with him). Hazrat Umar (may Allah be pleased with him) replied that the Messenger of Allah (peace and blessings be upon him) said: "Allah and His Messenger are the guardians of the one who has no guardian, and the maternal uncle is the heir of the one who has no heir."

Ibrahim narrates that Hazrat Umar (may Allah be pleased with him) made the maternal uncle the heir of the entire wealth. He (may Allah be pleased with him) said that this maternal uncle was both an uncle and a guardian.

It is narrated from Hazrat Abdullah bin Ubaid bin Umair (may Allah be pleased with him) that Hazrat Umar (may Allah be pleased with him) declared the maternal uncle to be the maternal uncle and the guardian (mawla) of the person of whom he is the guardian (wali).

Hazrat Miqdam (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "The maternal uncle is the heir of the person who has no other heir."
