Surah No. 13, Ar Raad, Part of Ayat No. 11

إِنَّ اللّهَ لاَ يُغَيِّرُ مَا بِقَوْمٍ حَتَّى يُغَيِّرُواْ مَا بِأَنْفُسِهِمْ وَإِذَا أَرَادَ اللّهُ بِقَوْمٍ سُوءًا

o فَلاَ مَرَدَّ لَهُ وَمَا لَهُم مِّن دُونِهِ مِن وَالٍ

Translation :

Verily ! Allah will never change the condition of the people until they change it themselves (with state of Goodness). But when Allah wills a punishment for them, there can be no turning back of it, and they will not find a protector besides Him.
