Saif ad-Dīn al-Malik al-ʿĀdil Abū Bakr b. Nāṣir ad-Dīn Muḥammad (Arabic: سيف الدين الملك العادل أبو بكر بن ناصر الدين محمد‎, known simply as al-Adil II) (c. 1221 – 9 February 1248) was the Ayyubid sultan of Egypt from 1238 to 1240. He was a Kurdish Ruler.When his father al-Kamil, nephew of Saladin, died in 1238, al-Adil II followed him somewhat unprepared. When the country plunged into anarchy, his exiled half-brother, as-Salih Ayyub, seized the opportunity and deposed him.
