Allah's Messenger (ﷺ) said, "Allah gives respite to the oppressor, but when He takes him over, He never releases him." Then he recited:-- "Such is the seizure of your Lord when He seizes (population of) towns in the midst of their wrong: Painful indeed, and severe is His seizure.' (11.102)
وَكَذَٰلِكَ أَخْذُ رَبِّكَ إِذَآ أَخَذَ ٱلْقُرَىٰ وَهِىَ ظَـٰلِمَةٌ ۚ إِنَّ أَخْذَهُۥٓ أَلِيمٌۭ شَدِيدٌ
Such is the ˹crushing˺ grip of your Lord when He seizes the societies entrenched in wrongdoing. Indeed, His grip is ˹terribly˺ painful and severe. (Surah 11. Hud verse 102)
Such like warnings abound in Qur'an and hadiths. These are to caution those who disobey Allah and create unrest in the world or are transgressors to the extent of making it difficult for others to breathe. If we look around, we will find such people abound and continue to live as per their own liking, completely oblivious of the limited time afforded to them to repent. And those who do not, one day the worst wrath of Allah befalls on them unannounced.
While Allah is merciful, He is also just. Those who persist in wrongdoing without repentance will face consequences, either in this life or the hereafter. The balance between mercy and justice ensures that while forgiveness is available, accountability is inevitable for those who do not repent.
"This is for what your own hands have sent before [to the Judgment], and because Allah is not ever unjust to His servants." Quran 3:182
Remember, Allah may forgive those who are slack or lazy in carrying out their personal obligations to Allah, except shirk. But those who hurt others unduly, will not be forgiven unless those who are wronged forgive them. This is like a ruler usurping public money and stuffing these in his coffers for his personal use will not be forgiven unless he returns the money of the people and seek their forgiveness. Such rulers and demagogues are being warned here.
If we are among such people, let us make good our loss by seeking forgiveness from those whom we have wronged, making good their losses, and then earnestly repent and seek Divine forgiveness. Remember, no one knows how much time he is left with!
May Allāh (سبحانه و تعالى) help us understand Qur'ān and follow the Sunnah of Prophet Muhammad ﷺ, which is embodiment of commandments of Allah contained in the Qur'ān. May Allah help us to be like the ones He loves and let our lives be lived helping others and not making others' lives miserable or unlivable. May all our wrong doings, whether intentional or unintentional, be forgiven before the angel of death knocks on our door.
