The 'knife' (sikkīn) is mentioned once in the Quran, playing a pivotal role in the narrative of Prophet Yusuf in Surah Yusuf, verse 12:31. According to search-discovered classical Islamic scholarship, this was no ordinary event. The wife of the 'Aziz, hearing the malicious gossip of the noblewomen about her infatuation with Yusuf, hosted a banquet. She provided each guest with a knife, ostensibly for cutting fruit like citrons. As classical commentators like Ibn Kathir and Al-Qurtubi explain, when she presented Prophet Yusuf, the women were so utterly overwhelmed and mesmerized by his divine beauty that they lost their senses and unconsciously cut their own hands. The knife, therefore, transforms from a simple utensil into a powerful symbol of astonishment and a testament to Yusuf's extraordinary, God-given beauty, instantly silencing the women's blame and validating the 'Aziz's wife's captivated state.
