Minor Sins will be Pardoned if One Refrains from Major Sins
Allah subhanahu wa ta’ala said in Ayah 30,
وَمَن يَفْعَلْ ذلِكَ عُدْوَناً وَظُلْماً
“And whoever commits that through aggression and injustice…” meaning, whoever commits what Allah has forbidden for him transgression and injustice – while knowing that it is forbidden for him, yet he still dares to commit it,
فَسَوْفَ نُصْلِيهِ نَاراً
“…We shall cast him into the Fire…” This Ayah carries a stern warning and a truthful promise. Therefore, every sane person should beware of it, those who hear the speech with full comprehension.
Allah subhanahu wa ta’ala then says in Ayah 31,
إِن تَجْتَنِبُواْ كَبَآئِرَ مَا تُنهَوْنَ عَنْهُ نُكَفِّرْ عَنْكُمْ سَيِّئَـتِكُمْ
“If you avoid the great sins which you are forbidden to do, We shall remit from you your (small) sins..” meaning, if you avoid the major evil deeds that you were prohibited We will forgive you the minor evil deeds and will admit you into Paradise. This is why Allah said,
وَنُدْخِلْكُمْ مُّدْخَلاً كَرِيماً
“..and admit you to a Noble Entrance (i.e. Paradise).”
There are several Hadiths on the subject of this honorable Ayah. Imam Ahmad recorded that Salman Al-Farisi said, “The Prophet said to me, `Do you know what the day of Al-Jumu`ah is?’ I said, `It is the day during which Allah brought together the creation of your father (Adam).’ He said,
لكِنْ أَدْرِي مَا يَوْمُ الْجُمُعَةِ، لَا يَتَطَهَّرُ الرَّجُلُ فَيُحْسِنُ طُهُورَهُ، ثُمَّ يَأْتِي الْجُمُعَةَ فَيُنْصِتُ حَتَّى يَقْضِيَ الْإمَامُ صَلَاتَهُ، إِلَّا كَانَ كَفَّارَةً لَهُ مَا بَيْنَهُ وَبَيْنَ الْجُمُعَةِ الْمُقْبِلَةِ، مَا اجْتُنِبَتِ الْمَقْتَلَة
“I know what the day of Jumu`ah is. Anyone who takes a bath and cleans himself as much as he can and then proceeds for the Friday prayer and remains quiet until the Imam finishes the prayer, all his sins in between the present and the next Friday will be forgiven, as long as major sins were avoided.” Al-Bukhari recorded similar wording from Salman Al-Farisi.
