The Prophet (SAWA) said, ‘The people of the Fire to experience the least pain will be wearing slippers of fire, whilst their brains will be boiling due to the [intensity of the] heat of their slippers.
رسولُ اللهِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ) : أدْنى أهلِ النّارِ عذاباً يَنْتَعِلُ بنَعْلَينِ مِن نارٍ ، يَغْلي دِماغُهُ مِن حَرارَةِ نَعْلَيهِ .
