Quran: Surah An-Nahl verse 61

"And if Allah had destroyed men for their iniquity, He would not leave on the earth a single creature, but He respites them till an appointed time; so when their doom will come they shall not be able to delay (it) an hour nor can they bring (it) on (before its time)."


Quran 16:61

Quran: Surah Ar-Ra'd verse 11

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 13:11
