The Messenger of Allah ﷺ said, "Two eyes will never be touched by the Fire, an eye that spent the night standing guard over the Muslims in the cause of Allah, and an eye that wept in solitude out of fear of Allah."
قال رسول الله ﷺ: عينان لا تمسهما النار: عين باتت تكلأ المسلمين في سبيل الله، وعين بكت في خلاء من خشية الله.
Narrated by Abu Yaala (4346), and from his route Diya in al-Mukhtara (2198), and Ibn Abu Asim in al-Jihad (147), both from Amr bin Dahhak bin Makhlad, who said, my father Dahhak bin Makhlad narrated to us, Shabib bin Bishr informed us, from Anas bin Malik, and he mentioned it. Its chain is hasan because of Shabib bin Bishr, for his hadith is hasan.On this subject there is also a report from Abu Rayhana, who said, "We were with the Messenger of Allah ﷺ on a military expedition. One night we came to a high piece of ground and spent the night there. We were struck by intense cold, so much so that I saw someone digging a hole in the ground to get into, throwing the hajafa (that is, the shield) over himself. When the Messenger of Allah ﷺ saw this from the people, he called out, "Who will guard us tonight? I will make for him a supplication that will bring great benefit." A man from the Ansar said, 'I will, Messenger of Allah.' He said, "Come closer." The man came closer, and he said, "Who are you?" The Ansari gave his name. The Messenger of Allah ﷺ then opened with the supplication and made it lengthy."Abu Rayhana said, "When I heard what the Messenger of Allah ﷺ had supplicated, I said, 'I am another man.' He said, "Come closer." I came closer, and he said, "Who are you?" I said, 'I am Abu Rayhana.' He then made a supplication for me, though less than what he had made for the Ansari, then he said, "The Fire is forbidden to an eye that has shed tears, or wept, out of fear of Allah, and the Fire is forbidden to an eye that has stayed awake in the path" of Allah." He then said, "The Fire is forbidden to another eye, a third one," but Muhammad bin Sumayr did not hear it.Narrated by Ahmad (17213), the wording is his, and Nasai (3117), and Hakim graded it sahih (2/83), and from him Bayhaqi (9/149), through several routes from Abdul-Rahman bin Shurayh, from Muhammad bin Sumayr Ruayni, from Abu Ali Janabi, or as some say, Tujaybi, from Abu Rayhana, who mentioned it. Nasai's version is very abridged.Hakim and Bayhaqi added, Abu Shurayh, that is, Abdul-Rahman bin Shurayh, said, "I later heard that he said, 'The Fire is forbidden to an eye that turned away in disgust from what Allah has forbidden, or an eye that was gouged out in the path of Allah.'"Hakim said, "Its chain is sahih, though the two of them (Bukhari and Muslim) did not narrate it."I say, in its chain is Muhammad bin Sumayr, also said to be Shumayr with a dotted shin, from whom no one narrated except Abdul-Rahman bin Shurayh, as Dhahabi stated in al-Mizan (3/580–581). No one deemed him reliable, except that Ibn Hibban mentioned him among his trustworthy narrators (7/398). For this reason, Ibn Hajar said, "Acceptable," meaning when corroborated, but I have not found any corroboration for him. As for Abu Ali Janabi, he is Amr bin Malik Hamdani, who is reliable.As for what is reported from Uqba bin Amir Juhani, attributed to the Prophet, "May Allah have mercy on the guard who stands watch," this is daif.Narrated by Ibn Majah (2769) and Darimi (2445), both through the route of Abdul-Aziz bin Muhammad Darawardi, from Muhammad bin Zaida, from Umar bin Abdul-Aziz, from Uqba bin Amir Juhani, who said, and he mentioned it.Darimi commented afterward, "Umar bin Abdul-Aziz never met Uqba bin Amir."Busiri said, "This chain is daif. Salih bin Muhammad was declared daif by Ibn Main, Abu Zura, Abu Hatim, Bukhari, Abu Dawud, Nasai, Ibn Adi, and others." Misbah Zujaja (3/157).Hakim also narrated it (2/86) through the route of Muhammad bin Salih bin Qays Azraq, from Salih bin Muhammad bin Zaida, from Umar bin Abdul-Aziz, from his father, from Uqba bin Amir, who mentioned it. He said, "Its chain is sahih."I say, it contains Salih bin Muhammad bin Zaida, who is daif as already mentioned. Furthermore, Aqeeli, in his entry on Yahya bin Rashid Simak, noted the disagreement over its chain, and stated that priority should be given to the version narrated without mention of his father, between Umar bin Abdul-Aziz and Uqba bin Amir.Ibn Hajar mentioned, in his entry on Qays bin Harith from Banu Tamim in al-Isaba (9/91–92), that in Musnad Umar bin Abdul-Aziz by Baghandi, the phrase "from his father" is not mentioned, and then he said, "This is the preserved version." There are other variant forms regarding the chain of this hadith as well.Ibn Hajar also said, in the third section under the letter qaf, in his entry on Qays bin Harith the successor (9/223), "Its core rests on Salih bin Muhammad, who is Abu Waqid Madani, one of the daif narrators."
