From the Quran
وَإِذَا جَآءَكَ ٱلَّذِينَ يُؤۡمِنُونَ بِـَٔايَٰتِنَا فَقُلۡ سَلَٰمٌ عَلَيۡكُمۡۖ كَتَبَ رَبُّكُمۡ عَلَىٰ نَفۡسِهِ ٱلرَّحۡمَةَ أَنَّهُۥ مَنۡ عَمِلَ مِنكُمۡ سُوٓءَۢا بِجَهَٰلَةٖ ثُمَّ تَابَ مِنۢ بَعۡدِهِۦ وَأَصۡلَحَ فَأَنَّهُۥ غَفُورٞ رَّحِيمٞ
And when those who believe in Our revelations come unto thee, say: Peace be unto you! Your Lord hath prescribed for Himself mercy, that whoso of you doeth evil through ignorance and repenteth afterward thereof and doeth right, (for him) lo! He is Forgiving, Merciful.
Al-An'am 6:54
This can be a gentle reminder that mercy has room for a mistake.
