What is the authenticity of the following ahadith 1)in which there is warning to those who listen songs/music and it is said melted steel will be put into their ears 2)one who sees others with desire and it is said fire will be put into his eyes. Please besides discussing authenticity(by quoting comments of various scholars)also quote these ahadith with references. May Allah reward you.

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

The first Hadeeth is not authentic; rather it is Baatil (false). Ibn Hazm labeled it as "fabricated". He cited it in his book Al-Muhalla on the authority of Anas as attributed to the Prophet, sallallaahu ‘alayhi wa sallam: "Whoever listens to a songstress (female singer), molten lead will be poured into his ears on the Day of Judgment." Ibn ‘Asaakir also cited it in his book Tareekh Dimashaq.

It has been reported that Imaam Ahmad ibn Hanbal was asked about the Hadeeth narrated by Ibn Al-Mubaarak on the authority of Maalik ibn Anas from Ibn Al-Munkadir from Anas that the Prophet, sallallaahu ‘alayhi wa sallam, said: "Whoever listens to a songstress, molten lead will be poured into his ears on the Day of Judgment." The questioner remarked that this Hadeeth was narrated by a man from Halab (Aleppo) who was highly praised. Imaam Ahmad replied: "This is Baatil (false)." [Al-Jaami‘ fi Al-‘Ilal wa Ma‘rifat Ar-Rijaal]

As for the second Hadeeth, it is fabricated. Al-Haythami cited it as part of a lengthy narration in his book Bughyat Al-Baahith under the heading "A speech falsely attributed to the Messenger of Allaah, sallallaahu ‘alayhi wa sallam, by Daawood ibn Al-Muhabbar." Part of the narration reads: "Whoever takes an unlawful look at a women, his eyes will be filled with fire, and Allaah will command him into Hellfire." Al-Haythami commented on that narration saying: "This is a fabricated Hadeeth."

The same narration of this speech was cited by Al-Booseeri in his book It-haaf Al-Khiyarah Al-Maharah under the heading "A speech falsely attributed by Daawood ibn Al-Muhabbar to the Messenger of Allaah, sallallaahu ‘alayhi wa sallam."

Allaah Knows best.
