Muslim narrated in his book Sahih Muslim: ''There is a Hadith about the fact that who murders one's own self does not commit Kufr. Jabir ibn Abdullah said: Tufayl ibn Amr approached the Prophet Muhammad before his departure to Medina, and offered him a stay in an impregnable fortress in Yemen, but the Prophet Muhammad insisted on going to Medina to meet his people. Later on, Tufayl ibn Amr followed the Prophet into Medina alongside a friend of his.
