قال ابن الجوزي ـ رحمه الله ـ: «فمنهم ـ أي: الحمقى ـ هبنَّقةُ، واسمه: يزيد بن ثروان ويقال: ابن مروان أحدُ بني قيس بن ثعلبة. ومِن حمقه أنه جعل في عنقه قلادةً مِن وَدْعٍ وعظامٍ وخزفٍ وقال: أخشى أن أُضِلَّ نفسي ففعلتُ ذلك لأعرفها به، فحُوِّلت القلادةُ ذات ليلةٍ مِن عنقه لعنق أخيه، فلمَّا أصبح قال: «يا أخي أنت أنا، فمَن أنا؟»
Ibn Al-Jawzi, may God have mercy on him, said: «Among them - meaning: the fools - is Habanaqa, and his name: Yazid bin Thurwan, and it is said: Ibn Marwan, one of the sons of Qais bin Tha'labah. And from his foolishness, he put a collar of Money cowry, bones, and earthenware on his neck and said: I am afraid that I will missed myself, so I did that to know her with him, so one night the necklace was turned from his neck to his brother's neck, so when he wake up he said: "Brother, you are me, who am I?"»
