The appointment of a new da'i at Alamut may have led the Seljuks to believe the Assassins were in a weakened position, and Ahmad Sanjar launched an attack on them in 1126. Led by Sanjar's vizier Mu'in ad-Din Kashi, the Seljuks again struck at Quhistan and also Nishapur in the east, and at Rudbar to the north. In the east, the Seljuks had minor successes at a village near Sabzevar, where the population was destroyed, their leader leaping from the mosque's minaret, and at Turaythirth in Nishapur, where the attackers "killed many, took much booty, and then returned." At best, the results were not decisive, but superior to the routing the Seljuks received in the north, with one expedition driven back, losing their previous booty, and another having a Seljuk commander captured. In the end, the Isma'ili position was better than before the offensive. In the guise of a peace offering of two Arabian horses, Assassins gained the confidence of Mu'in ad-Din Kashi and killed him in 1127.[31]
