وَالَّذِيْنَ اٰمَنُوْا مِنْۢ بَعْدُ وَهَاجَرُوْا وَجَاهَدُوْا مَعَكُمْ فَاُولٰۤىِٕكَ مِنْكُمْۗ وَاُولُوا الْاَرْحَامِ بَعْضُهُمْ اَوْلٰى بِبَعْضٍ فِيْ كِتٰبِ اللّٰهِ ۗاِنَّ اللّٰهَ بِكُلِّ شَيْءٍ عَلِيْمٌ ࣖ ( الأنفال: ٧٥ )
Wallazeena aamanoo mim ba'du wa haajaroo wa jaahadoo ma;akum faulaaa'ika minkum; wa ulul arhaami baduhum awlaa biba'din fee Kitaabil laah; innal laaha bikulli shai'in 'Aleem (al-ʾAnfāl 8:75)
And those who believed after [the initial emigration] and emigrated and fought with you – they are of you. But those of [blood] relationship are more entitled [to inheritance] in the decree of Allah. Indeed, Allah is Knowing of all things. (Al-Anfal  : 75)

Those who believed later on and emigrated and carried out Jihād alongwith you, then, they are joined with you. As for the womb-relatives, they are closer to one another according to the Book of Allah. Surely, Allah is aware of every thing.
