Verily, the Messenger of Allah ﷺ said: The least tormented of the inhabitants of the Fire would be he who would wear two shoes of Fire and his brain would boil on account of the heat of the shoes. (Using translation from Muslim 211)
"أدنى أهلِ النارِ عذابًا ينتعلُ بنعلين من نارٍ يغلى دماغُه من حرارةِ نَعْلَيه".
