لَهُۥ مُعَقِّبَٰتٌۭ مِّنۢ بَيْنِ يَدَيْهِ وَمِنْ خَلْفِهِۦ يَحْفَظُونَهُۥ مِنْ أَمْرِ ٱللَّهِ ۗ إِنَّ ٱللَّهَ لَا يُغَيِّرُ مَا بِقَوْمٍ حَتَّىٰ يُغَيِّرُوا۟ مَا بِأَنفُسِهِمْ ۗ وَإِذَآ أَرَادَ ٱللَّهُ بِقَوْمٍۢ سُوٓءًۭا فَلَا مَرَدَّ لَهُۥ ۚ وَمَا لَهُم مِّن دُونِهِۦ مِن وَالٍ
For him are angels ranged before him and behind him, who guard him by Allah's command. Lo! Allah changeth not the condition of a folk until they (first) change that which is in their hearts; and if Allah willeth misfortune for a folk there is none that can repel it, nor have they a defender beside Him.
Surah Ar-Ra'd(13:11)
