Surah Ar-Ra'd, Verse 11
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
Translation — Sahih International
For each one are successive [angels] before and behind him who protect him by the decree of Allah. Indeed, Allah will not change the condition of a people until they change what is in themselves. And when Allah intends for a people ill, there is no repelling it. And there is not for them besides Him any patron.
