Musannaf Ibn Abi Shaybah 29631 — Reports on the qasamah

Sayyiduna Abdullah bin Amr (may Allah be pleased with him) said: Huwayyisah bin Mas'ud, Muhayyisah bin Mas'ud, and Abdullah and Abd al-Rahman, the sons of so-and-so, these four set out to obtain provisions at Khaybar. Abdullah was attacked and killed. The narrator said: This was mentioned to the Prophet (peace and blessings be upon him), and the Prophet (peace and blessings be upon him) said: "You will swear fifty oaths, and you will then be entitled." They said: "O Messenger of Allah (peace and blessings be upon him), how can we swear when we were not present?" He (peace and blessings be upon him) said: "Then the Jews will clear themselves of you," meaning that the Jews will swear. They said: "O Messenger of Allah (peace and blessings be upon him), in that case the Jews will kill us." So the Prophet (peace and blessings be upon him) paid his blood money from his own funds.
