Narrated Imran ibn Husayn: A man came to the Prophet صلی اللہ علیہ وسلم and said: My son has died; what do I receive from his estate? He replied: You receive a sixth. When he turned away he called him and said: You receive another sixth. When he turned away, he called him and said: The other sixth is an allowance (beyond what is due). Qatadah said: They (the Companions) did not know the heirs with whom he was given (a sixth). Qatadah said: The minimum share given to the grandfather was a sixth.

Al-Hasan reported that Umar asked: Which of your knows what share the Messenger of Allah صلی اللہ علیہ وسلم had given to the grandfather from the estate? Maqil ibn Yasar said: The Messenger of Allah صلی اللہ علیہ وسلم gave him a sixth. He asked: Along with whom? He replied: I do not know. He said: You do not know; what is the use then?
