إِن تَجْتَنِبُوا۟ كَبَآئِرَ مَا تُنْهَوْنَ عَنْهُ نُكَفِّرْ عَنكُمْ سَيِّـَٔاتِكُمْ وَنُدْخِلْكُم مُّدْخَلًۭا كَرِيمًۭا
If you avoid the major sins which you are forbidden, We will remove from you your lesser sins and admit you to a noble entrance [into Paradise].
Righteous Deeds: Kaffarah کَفَارَہ of Minor Sins
Kaffarah is what makes amends, expiation. So the meaning is that righteous deeds will be taken as Kaffarah for minor sins which will thus be written off, resulting in reward instead of punishment and Paradise instead of Hell. This is in accordance with authentic ahadith where it has been stated that when a person makes wudu for salah, the act of washing each part of his body becomes the Kaffarah for sins; the washing of the face becomes the Kaffarah for sins committed by the eye, the ear, the nose; gargling becomes the Kaffarah for the sins of the tongue; washing feet a washes way the sins of the feet - and when he walks towards the masjid, every step he takes brings with it the Kaffarah of sins.
Major Sins are forgiven by Taubah تَوبَہ alone
From the verse, we find that the expiation of sins through righteous deeds such as wudu, salah and the rest, which appear in ahadith, concerns minor sins. As for major sins, they are not forgiven without Taubah (Repentance); and for minor sins, the condition is that one should have made the effort to stay away and remain safe from major sins. This leaves us with a note of warning - if someone, while staying involved in major sins, goes on performing his wudu' and salah, then this wudu' and salah and other righteous deeds will not at all expiate for even his minor sins, let alone the major ones. It is a warning that when a person appears on the fateful Day of Resurrection, carrying the heavy burden of his major and minor sins, he will find no helping hand to make his burden any lighter.
It will be recalled that some major sins were mentioned in the previous verses alongwith the warning of severe punishment for those who commit them. It is a peculiar style of the Holy Qur'an that when it warns of punishment against a sin, it is generally followed by some aspect of persuasion towards obedience.
In the present verse too, a particular Divine reward has been mentioned and people have been persuaded to acquire it by staying away from major sins, in which case, Allah Almighty will forgive their minor sins on His own. Thus, cleansed of all sins, major and minor, one could look forward to entering the home of honour and peace, the garden of Paradise.
The two kinds of sins
This verse tells us that there are two kinds of sins. Some of them are kabirah, that is, major sins; others are saghirah صغیرہ ، (termed as Saiyyat, in this verse) that is, minor sins. He, who musters enough courage and succeeds in staying away from major sins, has been given a promise by Allah Almighty that He will forgive his minor sins on His own.
Now, the act of staying away from major sins also includes the act of fulfilling all obligations (fard and wajib) because neglecting or abandoning obligations is a major sin in itself. Thus, we come to the conclusion that if one dutifully fulfills all obligations and succeeds in saving himself from all major sins, Allah Almighty will overlook his minor sins.
Defining Major and Minor Sins
The word, "Kaba'ir" used in the verse is the plural of 'kabirah' meaning 'major sins.' Before we proceed further, we should understand the nature and …
