It is not for the worshipers to test their Lord

Reference: Akhbaar al-Athkiyaa – Ibn al-Jowzee, p44

And from that which has been transmitted from ‘Eesaa (‘alayhis-salaam) is that Iblees came to him and said to him:

Do you not believe that nothing will afflict you except what Allaah has written for you?

He [replied]:

Yes [I do].

[So Iblees] said:

Then throw yourself off this mountain, for indeed if safety was prescribed for you, then you will be safe.

So he (‘Eesaa) said to him:

O cursed one! It is for Allaah (’Azza wa Jall) to test his worshipers, and not for his worshipers to test their Lord (’Azza wa Jall).
