Brief Verse Interpretation / Tafsir
If Allah wants to protect someone, He assigns angels before and behind him. No one can harm whom Allah has protected. If Allah has written obstacle in his path, no one can solve it besides Allah. Also, Allah does not change the condition of people until they make the effort to change it in themselves first.
“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.” Quran (Surah Raad, 11)
