Quran 57:16 — Iron (Al-Hadeed)

أَلَم يَأنِ لِلَّذينَ ءامَنوا أَن تَخشَعَ قُلوبُهُم لِذِكرِ اللَّهِ وَما نَزَلَ مِنَ الحَقِّ وَلا يَكونوا كَالَّذينَ أوتُوا الكِتٰبَ مِن قَبلُ فَطالَ عَلَيهِمُ الأَمَدُ فَقَسَت قُلوبُهُم ۖ وَكَثيرٌ مِنهُم فٰسِقونَ

Is it not time for those who believed to open up their hearts for GOD's message, and the truth that is revealed herein? They should not be like the followers of previous scriptures whose hearts became hardened with time and, consequently, many of them turned wicked.

[57:15] "Therefore, today no ransom can be taken from you, nor from those who disbelieved. Your abode is the fire; it is your lord, and miserable abode."

[57:17] Know that GOD revives the land after it had died. We thus explain the revelations for you, that you may understand.
