421 — (The Prophet—peace and blessings be upon him—said: “Whoever looks into a people’s home without their permission, they are permitted to put out his eye.” Agreed upon.) p. 307.
Authentic. It is fully referenced in al-Irwā (2228) from the hadith of Abū Hurayra. This makes it clear that al-Bukhārī did not narrate it in this wording, but rather as follows: “If a man were to look in upon you without permission, and you struck him with a pebble and put out his eye, no blame would fall upon you.”
422 — (The Prophet—peace and blessings be upon him—said: “Whoever listens in on a group’s conversation when they do not want him to hear it will have molten lead poured into both his ears on the Day of Resurrection.” Al-Bukhārī and others.) p. 307.
Authentic. Al-Bukhārī (4/361–362) narrated it, as did Abū Dāwūd (5024), al-Tirmidhī (1/325), al-Dārimī (2/298), Ahmad (1/246), and al-Tabarānī (3/129/2), through two routes from Ikrima, from Ibn Abbās, both tracing it to the Prophet with this wording. Qatāda differed from both narrators, reporting it from Ikrima, from Abū Hurayra. Ahmad (2/504) narrated it. Its chain is authentic provided that Qatāda heard it from Ikrima, since he was known to conceal omissions in his chains; otherwise, the preserved version is the hadith of Ibn Abbās. Al-Tirmidhī said: “A fair and authentic hadith.”
(Note) The book has “both his ears,” in the dual, as may be seen. The correct reading is “his ear,” in the singular; that is how it appears in all the sources cited above. The author merely followed al-Hāfiz al-Mundhirī in using the dual, for he likewise cited it that way in al-Targhīb (3/274). This was one of his errors—may Allah have mercy on him and forgive us and him!
423 — (Another hadith states: “Any man who draws aside a curtain and looks inside before being granted permission has crossed a boundary that he is not permitted to cross.” Ahmad and al-Tirmidhī.) p. 308.
