Is there a specific prayer for violating others’ rights (kul hakkı) in Islam?

In Islam, acts of worship are defined by Allah and His Messenger. Neither the Qur’an nor the Sunnah mention a specific prayer called “kul hakkı prayer.” The way to be absolved from violating someone’s rights is to return what is owed to the rightful owner and seek their forgiveness. One should also repent to Allah for any wrongdoing committed.

Regarding the rights of others, the Prophet Muhammad (peace be upon him) said: “Whoever has wronged his brother with regard to his honor or anything else, let him seek his forgiveness today before a day comes when there will be no gold or silver (to compensate with). If he has good deeds, a portion equal to his wrongdoing will be taken from them (and given to the wronged person). If he has no good deeds, the sins of the wronged person will be taken and loaded onto him.” (Bukhari, Mazalim, 10 [2449]; Riqaq, 48 [6534])
