Hasan al-Basri (may Allah have mercy on him) said: "In the time of ignorance, a man would make an agreement with another that 'I will be your heir and you will be mine,' so the one who made the agreement would receive one-sixth, then the rest of the heirs would divide the remaining wealth among themselves. Then Allah the Exalted abrogated this through 'But those of blood relationship are nearer to one another' [الأحزاب: 6]."

Mujahid (may Allah have mercy on him) said in the explanation of Allah Almighty’s statement ‘And for all We have made heirs’ [النساء: 33]: “What is meant are the ‘asabat (male relatives through the father).” And in the explanation of ‘And those with whom your right hands have made a covenant’: “What is meant are the allies.” And he gave the meaning of ‘So give them their share’ [النساء: 33] as: “Blood money, help, and maintenance.”
