Sadāq is the dowry and the money paid to the woman when getting married. Allah Almighty has made it a right that is due to the woman. Allah Almighty says: {Give women their marriage dowries graciously.} [Surat an-Nisā’: 4] In this Hadīth, the Tābi‘i Abu Salamah ibn ‘Abdur-Rahmān reports that he asked the Mother of the Believers, ‘Ā’ishah (may Allah be pleased with her): How much was the dowry paid by the Prophet (may Allah's peace and blessings be upon him) to his wives? She told him that it was twelve ’Uqiyyahs and one Nashsh. The ’Uqiyyah is forty dirhams, and the dirham refers to a coin made of pure silver, and one ’Uqiyyah is equal to 28.35 grams. The Nashsh is half a Uqiyyah. So, the dowry paid by the Messenger of Allah (may Allah's peace and blessings be upon him) to his wives was five hundred dirhams. It means that this is what the Prophet (may Allah's peace and blessings be upon him) mostly paid to his wives, simply because Al-Bukhāri narrated that the dowry of Safiyyah (may Allah be pleased with her) was emancipating her, and likewise the dowry of Juwayriyah bint al-Hārith was emancipating her. Moreover, An-Najāshi paid four thousand dirhams to Umm Habībah (may Allah be pleased with her) when he gave her in marriage to the Prophet (may Allah's peace and blessings be upon him). And no mention was made about the dowry of Zaynab bint Jahsh. So, the dowry does not have to be something specific; rather, it depends on everybody's ability and capability..
