Sheykh Fazlallah Astarabadi, the founder of the Hurufism sect was killed by Miran Shah, son of Timur in 1393. As a result, a group of followers of Hurufism in the Timurid territory started revenge-seeking fights against the Timurid rulers.[1][3]
While he wearing a shepherd's coat, Ahmed attacked Shahrukh Mirza, the brother of Miran Shah on the pretext of delivering a letter of complaint in Herats main mosque. The king was badly injured by the knife attack but ultimately survived. Ahmed was killed by a friend of Shahrukh Mirza, Ali Sultan Qouchin in 1426.[1]
After this incident, Shahrukh's emirs used this opportunity to repress the followers of Hurufism, leading to many being killed and even burned. A well-known calligrapher at Shahrukh's court was accused of having been a friend of Ahmed and was sentenced to prison. These persecutions eventually reached the point where the famous Persian poet, Qasem-e Anvar was exiled to Samarqand due to his diwan being found in Ahmed Lur's booth.[1]
