أَفَأَمِنَ ٱلَّذِينَ مَكَرُوا۟ ٱلسَّيِّـَٔاتِ أَن يَخْسِفَ ٱللَّهُ بِهِمُ ٱلْأَرْضَ أَوْ يَأْتِيَهُمُ ٱلْعَذَابُ مِنْ حَيْثُ لَا يَشْعُرُونَ
Are they who plan ill-deeds then secure that Allah will not cause the earth to swallow them, or that the doom will not come on them whence they know not?
Surah An-Nahl(16:45)
