وَعَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «مَنْ تَحَلَّمَ بِحُلْمٍ لَمْ يَرَهُ كُلِّفَ أَنْ يَعْقِدَ بَيْنَ شَعِيرَتَيْنِ وَلَنْ يَفْعَلَ وَمَنِ اسْتَمَعَ إِلَى حَدِيثِ قَوْمٍ وَهُمْ لَهُ كَارِهُونَ أَوْ يَفِرُّونَ مِنْهُ صُبَّ فِي أُذُنَيْهِ الْآنُكُ يَوْمَ الْقِيَامَةِ وَمَنْ صَوَّرَ صُورَةً عُذِّبَ وَكُلِّفَ أَنْ يَنْفُخَ فِيهَا وَلَيْسَ بِنَافِخٍ» . رَوَاهُ البُخَارِيّ

It is related from him that he said: I heard the Messenger of Allah (may Allah bless him and grant him peace) say, “Whoever claims to have dreamed a dream that he did not see will be charged with tying two barley grains together, and he will never be able to do so. Whoever listens in on people speaking when they dislike it or try to get away from him will have molten lead poured into his ears on the Day of Resurrection. Whoever makes an image will be punished and charged with breathing life into it, though he cannot do so.” Al-Bukhari transmitted it.

الْآنُكُ
The source uses the uncommon term al-anuk for the substance poured into the eavesdropper ears.
Is molten lead the intended sense of al-anuk in this wording?
