law of inheritance - Islam
 

In which Hijra was the law of inheritance revealed? 3H or 4H. Some sources mention the former; whereas, others mention the latter - which is correct?

if we refer to law of inheritence from Quran, its found in surah Al-Nisa chapter 4, verse # 11, 12 and 146.

verse 11 was revealed after battle of uhud in 3 A.H as narrated by "Narrated Jabir ibn Abdullah:

We went out with the Apostle of Allah (peace be upon him) and came to a woman of the Ansar in al-Aswaf. The woman brought her two daughters, and said: Apostle of Allah, these are the daughters of Thabit ibn Qays who was killed as a martyr when he was with you at the battle of Uhud, their paternal uncle has taken all their property and inheritance, and he has not left anything for them. What do you think, Apostle of Allah? They cannot be married unless they have some property. The Apostle of Allah (peace be upon him) said: Allah will decide regarding the matter. Then the verse of Surat an-Nisa was revealed: "Allah (thus) directs you as regards your children's (inheritance)." Apostle of Allah (peace be upon him) said: Call to me the woman and her husband's brother. He then said to their paternal uncle: Give them two-thirds and their mother an eighth, and what remains is yours."

"Sunan Abu Dawud 18:2885, See also: Sahih Bukhari 6:60:101, Sahih Bukhari 6:60:102, Sahih Bukhari 7:63:256 & Sahih Bukhari 8:80:735"

althou, i have not been able to find any particular dates, my guess will be 3 A.H, the year when the battle took place.
