was a miracle granted to the Prophet, peace and blessings be upon him, since they were unable to produce anything like it. “So fear the Fire”: that is, believe and, through faith, protect yourselves from the Fire, “whose fuel is people and stones.” Ibn Abbas and most exegetes said: this means sulphur stones, because they burn most intensely. It was also said: all stones; this indicates the enormity of that Fire. And it was said that it means idols, because most of their idols were carved from stone, as He says: “Indeed, you and what you worship besides Allah are the fuel of Hell” (al-Anbiya 21:98). “Prepared”: made ready “for the disbelievers.”
