يَا ابْنَ آدَمَ إِنَّكَ مَا دَعَوْتَنِي وَرَجَوْتَنِي غَفَرْتُ لَكَ عَلَى مَا كَانَ فِيكَ وَلَا أُبَالِي يَا ابْنَ آدَمَ لَوْ بَلَغَتْ ذُنُوبُكَ عَنَانَ السَّمَاءِ ثُمَّ اسْتَغْفَرْتَنِي غَفَرْتُ لَكَ وَلَا أُبَالِي يَا ابْنَ آدَمَ إِنَّكَ لَوْ أَتَيْتَنِي بِقُرَابِ الْأَرْضِ خَطَايَا ثُمَّ لَقِيتَنِي لَا تُشْرِكُ بِي شَيْئًا لَأَتَيْتُكَ بِقُرَابِهَا مَغْفِرَةً
O child of Adam, as long as you beseech Me and hope for Me, I shall forgive you whatever you have done, without minding in the slightest. O child of Adam, were your sins to reach up to the clouds of Heaven and then you asked forgiveness of Me, I should forgive you, without minding in the slightest. O child of Adam, even if you were to bring Me enough sins to fill the earth, but then you met Me without associating anything with Me, I should bring to you the selfsame measure of forgiveness.
