"O my sons,
do not enter from one door; Enter through different doors. However, I cannot save you from anything that is predetermined by God. To God belongs all judgments. I trust in Him, and in Him shall all the trusters put their trust." (Quran 12:67)
"When they went, they
entered in accordance with their father's instructions. Although this could not change anything decreed by God, Jacob had a private reason for asking them to do this;
For he possessed certain knowledge that we taught him, but most people do not know." (Quran 12:68)
The story of Joseph is said to contain much wisdom: "
In their history, there is a lesson for those who possess intelligence..." (Quran 12:111)
The advice seen here is "
Enter through different doors".
After contemplating, we can take this advice and put it to application through many different situations!
-In many cases,
Variety is better than being homogeneous.
-Make
more than one plan (e.g Plans: A, B, C etc.)
-Have
more than one perspective (e.g through Consultation 42:38 and 27:32)
-Save your work/data on
more than one place.
-Reserve
in many places, and not put our full fledged trust on one thing only (Except God of course!
