It is narrated from Sayyiduna Abu Rayhanah (may Allah be pleased with him) that once we participated in a battle with the Prophet (peace and blessings of Allah be upon him). At night, we reached a hill and spent the night there, and severe cold overtook us, to the extent that I saw some people digging holes in the ground and getting into them, then covering themselves with shields. When the Prophet (peace and blessings of Allah be upon him) saw the people in this condition, he announced, "Who will stand guard tonight? I will pray for him that Allah's grace will be with him." Upon this, an Ansari presented himself. The Prophet (peace and blessings of Allah be upon him) called him, and when he came near, asked, "Who are you?" He told his name. The Prophet (peace and blessings of Allah be upon him) began to pray for him and prayed abundantly. Sayyiduna Abu Rayhanah (may Allah be pleased with him) says that when I heard the Prophet's prayers, I stepped forward and submitted, "I am the second person." The Prophet (peace and blessings of Allah be upon him) said, "Come near." I came near. The Prophet (peace and blessings of Allah be upon him) asked, "Who are you?" I replied, "I am Abu Rayhanah." So the Prophet (peace and blessings of Allah be upon him) also prayed for me, though the prayers were somewhat less than those made for the Ansari. Then he said, "The fire of Hell is forbidden to the eye that weeps out of fear of Allah, and the fire of Hell is also forbidden to the eye that stays awake in the path of Allah." The narrator says that a third eye was also mentioned, but Muhammad bin Sameer could not hear it.
