Musannaf Ibn Abi Shaybah 35322 — What protects one from being killed

Ubaydullah bin Abdullah bin Utbah (may Allah have mercy on him) reports: When those who apostatized in the time of Sayyiduna Abu Bakr al-Siddiq (may Allah be pleased with him) apostatized, Sayyiduna Abu Bakr (may Allah be pleased with him) resolved to wage jihad against them. Sayyiduna Umar (may Allah be pleased with him) said: "Will you fight these people, when you have indeed heard the Messenger of Allah (peace and blessings be upon him) say: 'Whoever bears witness that there is none worthy of worship but Allah and that Muhammad (peace and blessings be upon him) is the Messenger of Allah, his wealth has become inviolable, except by its right, and his reckoning will be with Allah, the Lord of Honour'?!" Sayyiduna Abu Bakr (may Allah be pleased with him) said: "Shall I not fight the one who makes a distinction between the prayer and zakah? By Allah! I will certainly fight whoever makes a distinction between the two, until I bring them together." Sayyiduna Umar (may Allah be pleased with him) said: So we fought alongside him, and he was truly rightly guided. Then, when he had gained victory over those of them he overcame, he said: "Choose from me one of two things: either a war of expulsion or a disgraceful settlement." They said: "The war of expulsion we have understood. What is meant by this disgraceful settlement?" He said: "That you bear witness concerning our slain that they are certainly in Paradise, and bear witness concerning your slain that they are certainly in Hell." And they did so.
