Is it necessary to repeat repentance if one does not feel at ease after repenting? And will Allah conceal His servant in the Hereafter as He concealed him in this world? And is it obligatory to inform those who were lied to of the truth? And is a person punished for their sins while being seventeen years old?

Repentance is obligatory in all circumstances. It is the first and the last of spiritual stations, and the servant, the seeker of truth, does not abandon it until death. This is because Allah commanded the believers to repent and linked success to it. And whoever does not repent is a wrongdoer. The Prophet, peace and blessings be upon him, used to repent and seek Allah's forgiveness more than seventy times a day. As for the question of repeating repentance, there is no basis for it. The one who repents hopes for Allah's concealment and forgiveness. Informing those who were lied to about the lie is not obligatory unless harm results from it. Weeping is not a condition for the validity of repentance.
