Read reminders about mercy together with the surrounding calls to repentance and returning to Allah. For example, Az-Zumar 39:53 is followed by a call to turn back in 39:54. Keeping that connection visible helps avoid presenting forgiveness as a quotation with all responsibility removed. These entries offer starting points for reading, not a ruling on any individual person’s situation. Practical repair may include acknowledging harm and taking steps to put it right. The source links let you check both wording and context. Our reflections are clearly separated from the Qur’anic text and should not be quoted as revelation.
Say: O My slaves who have been prodigal to their own hurt! Despair not of the mercy of Allah, Who forgiveth all sins. Lo! He is the Forgiving, the Merciful.
And let not those who possess dignity and ease among you swear not to give to the near of kin and to the needy, and to fugitives for the cause of Allah. Let them forgive and show indulgence. Yearn ye not that Allah may forgive you? Allah is Forgiving, Merciful.
