وَإِذَا جَاءكَ الَّذِينَ يُؤْمِنُونَ بِآيَاتِنَا فَقُلْ سَلاَمٌ عَلَيْكُمْ كَتَبَ رَبُّكُمْ عَلَى نَفْسِهِ الرَّحْمَةَ أَنَّهُ مَن عَمِلَ مِنكُمْ سُوءًا بِجَهَالَةٍ ثُمَّ تَابَ مِن بَعْدِهِ وَأَصْلَحَ فَأَنَّهُ غَفُورٌ رَّحِيمٌ
﴿٥٤﴾
سورة الأنعام
(6/54) When those who believe in Our Verses come to you, say: “Peace be on you”. Your Lord has written Mercy on Himself. So that if any one of you does evil in ignorance, then repents (before his religious guide-Murshid) and improves (does the soul’s cleansing), then He (Allah) is Oft-Forgiving, (the One who converts evil deeds into merits), Most Merciful (the One who sends down the light of mercy).
Surah Al-An'am
