الَّذِينَ يَجْتَنِبُونَ كَبَائِرَ الْإِثْمِ وَالْفَوَاحِشَ إِلَّا اللَّمَمَ إِنَّ رَبَّكَ وَاسِعُ الْمَغْفِرَةِ هُوَ أَعْلَمُ بِكُمْ إِذْ أَنشَأَكُم مِّنَ الْأَرْضِ وَإِذْ أَنتُمْ أَجِنَّةٌ فِي بُطُونِ أُمَّهَاتِكُمْ فَلَا تُزَكُّوا أَنفُسَكُمْ هُوَ أَعْلَمُ بِمَنِ اتَّقَى
Those who avoid major sins and indecencies, apart from [minor and occasional] lapses. Indeed your Lord is expansive in [His] forgiveness. He knows you best since [the time] He produced you from the earth and since you were foetuses in the bellies of your mothers. So do not flaunt your piety: He knows best those who are Godwary.
Agha Ali Puya Commentary
Commentary on Quran 53:32
[Pooya/Ali Commentary 53:32] Lamam stands for the intention (to sin) and the sins committed before coming into the fold of Islam, most likely to be forgiven after repentance and amended conduct. Allah's attributes of mercy and forgiveness are unlimited. They come into action without our asking if we surrender our wills to Him. Our prayer helps us to surrender our wills to Him. As Allah knows our inmost being, it is absurd to justify ourselves, either by pretending that we are better than we are, or by finding excuses for our misconduct. If we try to safeguard ourselves against evil with full awareness of the laws made by Him He will appreciate our striving and may forgive us.
