[2] In 1082, the caliph sent Fakhr ad-Dawla[3][4] to Isfahan, laden with gifts and over 20,000 dinars, to negotiate marriage with Malik-Shah's daughter.

[3] Malik-Shah was grieving the death of his son Da'ud and did not take part in the negotiations; rather, Fakhr ad-Dawla went to Nizam al-Mulk.

[4] Eventually, Terken Khatun agreed to the marriage, but with heavy conditions imposed on al-Muqtadi: in return for marrying the Seljuk princess, al-Muqtadi would pay 50,000 dinars plus an additional 100,000 dinars as mahr (bridal gift), give up his current wife (Sifri Khatun, Malik's sister) and concubines, and agree to not have sexual relations with any other woman.

[3] By agreeing to Terken Khatun's terms, Fakhr ad-Dawla was putting al-Muqtadi at a severe disadvantage while also benefitting the Seljuks considerably.

[3] Mah-i Mulk became al-Muqtadi's second wife, Her father gave his consent and the marriage contract was concluded.
