It is narrated from Sayyiduna Ibn Amr, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "Whoever raises a weapon against us or lies in ambush on the road is not one of us, and whoever is killed in any other manner, it is called 'shibh-i-amd' (quasi-intentional killing), and its blood money will be aggravated (increased). However, in this case, the killer will not be killed, and it is like the sacred month in terms of sanctity and neighborliness."
