Hazrat Sha'bi (may Allah have mercy on him) said: "If a woman marries based on the decision of someone or the decision of her family, and then she or the decision-maker commits injustice, then the woman should be given a mahr like hers—neither more nor less."

It is narrated from Hazrat Sha'bi (may Allah have mercy on him) that Sayyiduna Amr bin Harith (may Allah be pleased with him) proposed marriage to the daughter of Sayyiduna Adi bin Hatim (may Allah be pleased with him). Adi said: "I will marry her off according to my decision." Amr disliked that he might set a condition regarding his house or something else. Later, Amr expressed his willingness for the marriage. Adi said: "I will not make any such decision about which Allah, the Exalted, will question me." Thus, he decided on ten uqiyah, that is, four hundred and eighty dirhams.

Sayyiduna Adi bin Hatim (may Allah be pleased with him) said: "I would not decide for more than what the Messenger of Allah (peace and blessings be upon him) gave in marriage or was given to him."

When Sayyiduna ‘Adi (may Allah be pleased with him) made a judgment for four hundred and eighty dirhams, Sayyiduna ‘Amr bin Harith (may Allah be pleased with him) sent him thirty thousand. ‘Adi distributed all of it among those who were present, and he was also wearing a cloak over himself. When ‘Amr bin Harith learned that everything had been distributed, he sent the dowry for his daughter and the things she needed. The name of that girl was Asadah bint ‘Adi.

Sayyiduna Zaid bin Aslam (may Allah have mercy on him) said: "It is written in some books that the dowry of a virgin is forty dirhams and the dowry of a widow is twenty dirhams, so that no one may say that I do not get anything for marriage and then commit adultery."

Hasan al-Basri (may Allah have mercy on him) said: "Whatever is mutually agreed upon for marriage, that is the mahr (dowry)."
