Assalamualaikum
Almighty allah says that "he guides whom he wants and misguides whom he wishes" besides he also says that "nobody will be subjected to injustice" then why do he misguide some people and guide some other? Allah knows who will worship him despite of this why does he test us?" When he know whether will the person succeed or not.
Jazakallah

Assalamualaikum brother afaroo
Thank you
I understand that allah has control over every thing as he is our creator but why does he misguide the people? When there will be no injustice to any one. I heard that "allah saved Nuh alaihissalam and his family and all the believers with him except his wife because allah wanted to keep her among the backward people". Why? What was her mistake?
Jazakalla hu khair
