Al-Ma'arij 70:15–18

كَلَّا ۖ إِنَّهَا لَظَىٰ نَزَّاعَةً لِّلشَّوَىٰ (By no means! It is the flaming fire, that will pull out the skin of the scalp...70:15, 16). The pronoun of innaha (it) refers to 'Fire' and the word laza means 'the flaming fire'. The word shawa is the plural of shawah and it refers to 'the scalp or the skin of the human head, and also the skin of the hands and the legs'. The verse describes that the Fire of Hell would be a raging blaze that will pull out the skin of the scalp.

تَدْعُو مَنْ أَدْبَرَ‌ وَتَوَلَّىٰ وَجَمَعَ فَأَوْعَىٰ (It will call him who had turned his back and fled away (from the truth.) and accumulated (wealth) and hoarded (it)....70:17, 18). The phrase 'accumulated wealth' signifies 'wealth accumulated by unlawful means' and the phrase 'hoarded it' signifies 'not fulfilling the pecuniary obligations as imposed by the Shari` ah', as is confirmed by authentic ahadi'th.
