Narrated by Jubair bin Mutim (radiallaahu `anhu)
I and ‘Uthman bin ‘Affan (radiallaahu `anhu) went to Allah’s Apostle (sallallaahu `alayhi wasallam) and said, “O Allah’s Apostle! You have given to Bani Al-Muttalib and left us although they and we are of the same kinship to you.” Allah’s Apostle (sallallaahu `alayhi wasallam) said, “Bani Muttalib and Bani Hashim are one and the same.” The Prophet (sallallaahu `alayhi wasallam) did not give a share to Bani Abd Shams and Bani Naufal.
(Ibn Ishaq said, “Abd Shams and Hashim and Al-Muttalib were maternal brothers and their mother was ‘Atika bint Murra and Naufal was their paternal brother.)
The image above shows the four sons of Abd Manaf: Al-Muttalib, Hashmi, Nawfal (paternal brother) and Abd Shams. Prophet Muhammad (sallallaahu `alayhi wasallam) himself was from Hashim (as shown), Uthman ibn Affan (radiallaahu `anhu) was from Abd Shams and Jubair ibn Mut’im (radiallaahu `anhu) was from Nawfal.
When Prophet (sallallaahu `alayhi wasallam) distributed the khumus among Banu Muttalib and Banu Hashim and not the other two clans, Uthman and Jubair (radiallaahu `anhumaa) came to him with this concern – how come they got it and we didn’t when we have the same relationship to the Prophet (sallallaahu `alayhi wasallam) as them? So the Prophet (sallallaahu `alayhi wasallam) said that Banu Hashim and Banu Muttalib are one and the same – meaning (according to commentators) they were always together in kufr and Islam. Nothing separated them. That’s why they get a share and others don’t.
