Shajar al-Durr wanted sole rule of Egypt. She concealed Sultanate affairs from Aybak; she also prevented him from seeing his other wife and insisted that he should divorce her. Instead, Aybak, who needed to form an alliance with a strong Emir who could help him against the threat of the Mamluks who had fled to Syria, decided in 1257 to marry the daughter of Badr ad-Din Lo'alo'a the Ayyubid Emir of al-Mousil. Badr ad-Din Lo'alo'a warned Aybak that Shajar al-Durr was in contact with an-Nasir Yusuf in Damascus. Shajar al-Durr, feeling at risk and betrayed by Aybak, the man whom she had made a Sultan, had him murdered by servants while he was taking a bath. He had ruled Egypt for seven years.
