"The wife of Sa'd bin Ar-Rabi came with her two daughters from Sa'd to he Messenger of Allah ﷺand said; O Messenger of Allah ﷺ! these two are daughters of Sa'd bin Ar-Rabi who fought along with you on the day of Uhud and was martyred. Their uncle took their wealth, without leaving any wealth for them, and they will not be married unless they have wealth.' He said: 'Allah will decide on that matter.' The ayah about inheritance was revealed, so the Messenger of Allah ﷺ sent (word) to their Uncle saying: Give the two daughters of Sa'd two thirds, and give their mother one eighth, and whatever remains, then it is for you.'
