What Is Sarkashi
Commiting a major sin is sarkashi. However, situation and condition of a person may make his case less severe and he may get a lesser punishment, not the punishment of sarkashi. It will be judged by God.
A major sin is not forgiven until one repents because it is sarkashi. Allah has told us the if we avoid the major sins, He will forgive the minor sins. See verse: 4: 29-31 یٰۤاَیُّہَا الَّذِیۡنَ اٰمَنُوۡا لَا تَاۡکُلُوۡۤا اَمۡوَالَکُمۡ بَیۡنَکُمۡ بِالۡبَاطِلِ اِلَّاۤ اَنۡ تَکُوۡنَ تِجَارَۃً عَنۡ تَرَاضٍ مِّنۡکُمۡ ۟ وَ لَا تَقۡتُلُوۡۤا اَنۡفُسَکُمۡ ؕ اِنَّ اللّٰہَ کَانَ بِکُمۡ رَحِیۡمًا ﴿۲۹﴾ وَ مَنۡ یَّفۡعَلۡ ذٰلِکَ عُدۡوَانًا وَّ ظُلۡمًا فَسَوۡفَ نُصۡلِیۡہِ نَارًا ؕ وَ کَانَ ذٰلِکَ عَلَی اللّٰہِ یَسِیۡرًا ﴿۳۰﴾ اِنۡ تَجۡتَنِبُوۡا کَبَآئِرَ مَا تُنۡہَوۡنَ عَنۡہُ نُکَفِّرۡ عَنۡکُمۡ سَیِّاٰتِکُمۡ وَ نُدۡخِلۡکُمۡ مُّدۡخَلًا کَرِیۡمًا “Believers! Do not consume one another’s wealth through evil means, except if it is trading by mutual consent, through which some wealth can be acquired, and do not kill one another. No doubt, God is extremely Merciful to you. [74] And [remember that] those who do this through injustice and oppression, We shall definitely cast them into a seething fire, and this is very easy for God. [Abstain from these sins because] things from which you are being stopped, if you keep abstaining from their major sins, We shall erase your minor sins from your account and admit you into a place of honour.” Now, the sin of sarkashi varies in intensity for different people. One outrightly denies it, the other does not bother about it, they are the rebels of the first degree. A third one is overwhelmed by one’s emotions and commit a major sin, in this case, if one immediately repents after the sin, one is forgiven, however, if one delays, one make his case worse. see 4: 17-18 إِنَّمَا التَّوْبَةُ عَلَى اللَّهِ لِلَّذِينَ يَعْمَلُونَ السُّوءَ بِجَهَالَةٍ ثُمَّ يَتُوبُونَ مِن قَرِيبٍ فَأُولَٰئِكَ يَتُوبُ اللَّهُ عَلَيْهِمْ ۗ وَكَانَ اللَّهُ عَلِيمًا حَكِيمًا ‎﴿١٧﴾‏ وَلَيْسَتِ التَّوْبَةُ لِلَّذِينَ يَعْمَلُونَ السَّيِّئَاتِ حَتَّىٰ إِذَا حَضَرَ أَحَدَهُمُ الْمَوْتُ قَالَ إِنِّي تُبْتُ الْآنَ وَلَا الَّذِينَ يَمُوتُونَ وَهُمْ كُفَّارٌ ۚ أُولَٰئِكَ أَعْتَدْنَا لَهُمْ عَذَابًا أَلِيمًا “[It should, however, remain clear that] God’s responsibility to forgive is only for those who commit a sin while being overwhelmed with emotions and then repent soon. So, it is they to whom God shows His mercy and accepts their repentance and God is All-Knowing and Wise. On the contrary, there is no repentance for those who sin all their lives and, when the time of death approaches for any of them, he says: “Now I do repent!” Similarly, there is no repentance for those also who die as disbelievers. It is these for whom We have prepared a grievous punishment.” laziness is a lame excuse, but it does not make one the sarkash of the first degree for whom the eternal hellfire is destined. However, the lesser sarkash, too, will go to hell and come out after serving their sentence.
