Shajar al-Durr claimed that Aybak died suddenly during the night but his Mamluks (Mu'iziyya), led by Qutuz, did not believe her and the servants involved confessed under torture. Shajar al-Durr and the servants were arrested and Aybak's Mamluks (the Mu'iziyya Mamluks) wanted to kill her, but the Salihiyya Mamluks protected her and she was taken to the Red Tower where she stayed. The son of Aybak, the 15-year-old al-Mansur Ali, was installed by the Mu'ziyyah Mamluks as the new Sultan. On 28 April, Shajar al-Durr was stripped and beaten to death with clogs by the bondmaids of al-Mansur Ali and his mother. Her naked body was found lying outside the Citadel. According to the historian Ibn Iyas, Shajar al-Durr was dragged from her feet and thrown from the top naked, with a cloth around her waist. She stayed in the moat for three days, unburied, until one night a mob came and took off the cloth around her waist because it was silk with pearls and had a smell of musk. The servants who were involved in the killing of Aybak were executed.
