Verse 53 of Surah Az-Zumar, often called the most hopeful verse in the Quran.
Allah tells those who have wronged themselves not to lose hope in His mercy, for He forgives all sins. It is a direct, comforting reminder that the door of repentance stays open. Scholars have long pointed to it as one of the most reassuring verses for anyone weighed down by past mistakes.

۞ قُلْ يَٰعِبَادِىَ ٱلَّذِينَ أَسْرَفُوا۟ عَلَىٰٓ أَنفُسِهِمْ لَا تَقْنَطُوا۟ مِن رَّحْمَةِ ٱللَّهِ ۚ إِنَّ ٱللَّهَ يَغْفِرُ ٱلذُّنُوبَ جَمِيعًا ۚ إِنَّهُۥ هُوَ ٱلْغَفُورُ ٱلرَّحِيمُ
Qul yaa'ibaadiyal lazeena asrafoo 'alaaa anfusihim laa taqnatoo mirrahmatil laah; innal laaha yaghfiruz zunooba jamee'aa; innahoo Huwal Ghafoorur Raheem
Katakanlah (wahai Muhammad): "Wahai hamba-hambaKu yang telah melampaui batas terhadap diri mereka sendiri (dengan perbuatan-perbuatan maksiat), janganlah kamu berputus asa dari rahmat Allah, kerana sesungguhnya Allah mengampunkan segala dosa; sesungguhnya Dia lah jua Yang Maha Pengampun, lagi Maha Mengasihani.
