To all who are broken-hearted after being hurt unjustly by another,
If you believe in Allah, then you must believe in Heaven and Hell.
If you believe in Heaven and Hell, then you must believe that there are people destined for each.
If you believe that there are people destined for each, then you must believe that those who disobey Allah and harm His creation with impunity are destined for Hell.
If you believe THAT, then *STOP* obsessing over getting justice against whoever hurt you, betrayed you, lied to you, broke your heart, stole from you, etc.
REAL JUSTICE MAY BE DELAYED IN THIS LIFETIME, BUT IT IS *NEVER* EVADED.
So do NOT become vengeful or vindictive, or even resentful. Rather, be at peace with the knowledge that no matter what happens in this world, the All-Knowing, All-Seeing, Most Just will make certain in the next life that every debt that is due is paid, and every heart that is broken is restored, and every wrong action is redressed.
Carry on with your life, continue to be a good person, fulfill your duties and responsibilities, and show gratitude that you're NOT like the one who caused you harm; a delusional fool who disobeys God, hurts His creation, and actually thinks he/she will ever get away with it unscathed!
The Beloved ﷺ of Allah ﷻ said:
مَنْ ضَارَّ ضَارَّ اللَّهُ بِهِ وَمَنْ شَاقَّ شَاقَّ اللَّهُ عَلَيْهِ
"Whoever harms others, then Allah will harm him. Whoever is harsh with others, then Allah will be harsh with him." (Tirmidhi)
مَنْ أَحَبَّ أَنْ يُزَحْزَحَ عَنْ النَّارِ وَيَدْخُلَ الْجَنَّةَ فَلْتُدْرِكْهُ مَنِيَّتُهُ وَهُوَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ وَيَأْتِي إِلَى النَّاسِ مَا يُحِبُّ أَنْ يُؤْتَى إِلَيْهِ
"Whoever would love to be saved from Hellfire and entered into Paradise, then let him die with faith in Allah and the Last Day and let him treat people the way he would love to be treated." (Muslim)
أَلَا أُخْبِرُكُمْ بِخَيْرِكُمْ مِنْ شَرِّكُمْ خَيْرُكُمْ مَنْ يُرْجَى خَيْرُهُ وَيُؤْمَنُ شَرُّهُ وَشَرُّكُمْ مَنْ لَا يُرْجَى خَيْرُهُ وَلَا يُؤْمَنُ شَرُّهُ
"Shall I not tell you what distinguishes the best of you from the worst of you? The best of you are those from whom goodness is expected and people are safe from their evil. The worst of you are those from whom goodness is not expected and people are not safe from their evil." (Tirmidhi)
