It is narrated from Sayyiduna Nu'aym bin Mas'ud al-Ashja'i (may Allah be pleased with him); he said: I heard the Messenger of Allah (peace and blessings be upon him) say to the two envoys of Musaylimah (the Liar), when he (peace and blessings be upon him) had read Musaylimah's letter: "What do you two say?" They said: We say as he (Musaylimah) said. So he (peace and blessings be upon him) said: "By Allah, were it not the rule that envoys are not killed, I would have struck off both your necks." This hadith is sahih (authentic) on the condition of Muslim, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Ali (may Allah be pleased with him); he said: When the fighting grew fierce and the two armies met face to face, we would take shelter behind the Messenger of Allah (peace and blessings be upon him) (to protect ourselves from the enemy's attacks), and none of us would be as close to the enemy as the Messenger of Allah (peace and blessings be upon him) was (because of his courage). This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
