Our Internal Sense of Calm and Stability (ITMINAN=E-QALB اطمينان قلب) should depend on the Limits we set for ourselves, rather than how OTHERS perceive or validate our CHOICES..
And who can tell us the LIMITS that we can SET for ourselves to SUCCESSFULLY ACHIEVE PEACE?
Yes, OUR CREATOR; WHO ECONOMIZES our EFORTS and HIMSEL CLEARLY SETS UNALTERABLE Boundaries for us. Also, He tells us, “Don’t play near the Boundaries”, as the chances of Crossing the Boundaries significantly increase and we then will face FOUL (destructive consequences).
RESULTS OF FOLLOWING THE DIVINELY SET BOUNDARIES:
4: 13 (An-Nisaa)

تِلْكَ حُدُودُ اللَّهِ وَمَن يُطِعِ اللَّهَ وَرَسُولَهُ يُدْخِلْهُ جَنَّاتٍ تَجْرِي مِن تَحْتِهَا الْأَنْهَارُ خَالِدِينَ فِيهَا وَذَٰلِكَ الْفَوْزُ الْعَظِيمُ

These are boundaries set by Allah. Those who obey Allah and His Messenger, He will admit them into Gardens with rivers flowing beneath to abide therein. That is the Supreme Success.
RESULTS OF DISOBEYING ALLAH’S SET BOUNDARIES:
4: 14 (An-Nisaa)

وَمَن يَعْصِ اللَّهَ وَرَسُولَهُ وَيَتَعَدَّ حُدُودَهُ يُدْخِلْهُ نَارًا خَالِدًا فِيهَا وَلَهُ عَذَابٌ مُّهِينٌ

But those who disobey Allah and His Messenger and trespass His ordained boundaries, He will admit them to Fire to abide therein, and for them is a humiliating punishment.
