۞ أَوَلَمْ يَرَوْا۟ أَنَّ ٱللَّهَ ٱلَّذِى خَلَقَ ٱلسَّمَٰوَٰتِ وَٱلْأَرْضَ قَادِرٌ عَلَىٰٓ أَن يَخْلُقَ مِثْلَهُمْ وَجَعَلَ لَهُمْ أَجَلًۭا لَّا رَيْبَ فِيهِ فَأَبَى ٱلظَّٰلِمُونَ إِلَّا كُفُورًۭا
Have they not seen that Allah Who created the heavens and the earth is Able to create the like of them, and hath appointed for them an end whereof there is no doubt? But the wrong-doers refuse aught save disbelief.
