«مَنْ خَشِيَ الرَّحْمَنَ بِالْغَيْبِ وَجَاءَ بِقَلْبٍ مُنِيبٍ»
“Whoever has feared the All-Merciful while in the domain unseen, and who comes to his Lord with a penitent heart longing to be redeemed.”
Fuḍayl commentated on this verse and said:
«الْمُنِيبُ الَّذِي يَذْكُرُ ذَنْبَهُ فِي الْخَلْوَةِ فَيَسْتَغْفِرُ مِنْهُ»
“The one with a penitent heart longing to be redeemed is he who remembers his misdeeds in seclusion and seeks forgiveness for them.”
 Q, 50:33.
