The Madinan Period, Part 2: The Masjid, the Brotherhood and the Covenant
Section 17 of 23 · The Life of the Prophet Muhammad: The Madinan Period
A Nation Founded on Faith, Not on Blood
This relationship of brotherhood was in pairs — one Muhājir and one Anṣārī — and it carried on for a while, until the situation of the Muhājirūn improved, and then it was dissolved; the general brotherhood of the Ummah remained. So this specific type of brotherhood was dissolved, and inheritance laws now only applied to the blood relatives.
وَٱلَّذِينَ ءَامَنُوا۟ مِنۢ بَعْدُ وَهَاجَرُوا۟ وَجَـٰهَدُوا۟ مَعَكُمْ فَأُو۟لَـٰٓئِكَ مِنكُمْ ۚ وَأُو۟لُوا۟ ٱلْأَرْحَامِ بَعْضُهُمْ أَوْلَىٰ بِبَعْضٍ فِى كِتَـٰبِ ٱللَّهِ ۗ إِنَّ ٱللَّهَ بِكُلِّ شَىْءٍ عَلِيمٌۢ
“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.” (8:75)
There is one lesson to learn from this topic of brotherhood: a new community was being developed based on a new bond. In Arabia, the bonds that existed were the bonds of blood relationship, the bonds of economic relationships; but now a nation was born based on faith. It was a faith-based community.
