sincerely seek forgiveness from Allah عَزَّوَجَلَّ. After seeking forgiveness, he should perform some good deeds because good deeds erase sins. If he has violated the rights of people, then this has three situations:

1.         These rights are only related to credit such as the price of something that has been bought, wage of a labour or the Mahr (monetary dower) of a wife etc. In this case, repentance should be made like this: A person should fulfil these rights or should apologize to the person whose rights he has violated.

2.         These rights are only related to cruelty such as to beat up someone, to abuse someone or to commit backbiting against a person which he gets to know about. In this case, repentance should be made like this: A person should only apologize to the one whose rights he has violated.

3.         These rights are related to both—credit and cruelty such as to steal, seize or rob someone of his possession, to take a bribe from someone, to charge interest on money or win money in gambling etc. In this case, repentance should be made like this: A person should fulfil the rights as well as apologize to the person whose rights he has violated. If the conditions of repentance are fulfilled, repentance will definitely be accepted, because it is the promise of Allah عَزَّوَجَلَّ and to go back on His promise is not worthy of His blessed glory. (Siraat-ul-Jinaan, vol. 4, pp. 230)

گر تُو ناراض ہوا میری ہلاکت ہوگی               ہائے! میں نارِ جہنّم میں جلوں گا یا ربّ

عَفو کر اور سَدا کے لئے راضی ہوجا             گر کرم کردے تو جنَّت میں رہوں گا یا رَبّ

صَلُّوۡا عَلَى الۡحَبِيۡب       صَلَّى اللّٰهُ تَعَالٰى عَلٰى مُحَمَّد

Dear Islamic brothers! The mercies of Allah عَزَّوَجَلَّ are countless, therefore, whenever we commit sins, we should immediately repent and humbly beg
