الذنوب بجميع أنواعها يمكن أن تُكفَّر بالتوبة النصوح. قال الله تعالى: {يَا أَيُّهَا الَّذِينَ آمَنُوا تُوبُوا إِلَى اللَّهِ تَوْبَةً نَّصُوحًا عَسَىٰ رَبُّكُمْ أَن يُكَفِّرَ عَنكُمْ سَيِّئَاتِكُمْ وَيُدْخِلَكُمْ جَنَّاتٍ تَجْرِي مِن تَحْتِهَا الْأَنْهَارُ}. (التحريم: 8)

A ---All sorts of sins can be expiated through sincere repentance. Allah the Almighty says: {O you who believe! Turn to Allah with sincere repentance! It may be that your Lord will expiate from you your sins, and admit you into Gardens under which rivers flow (Paradise)}. (At-Tahrim, 8)

قال الله تعالى: {إِلَّا مَن تَابَ وَآمَنَ وَعَمِلَ عَمَلًا صَالِحًا فَأُولَٰئِكَ يُبَدِّلُ اللَّهُ سَيِّئَاتِهِمْ حَسَنَاتٍ ۗ وَكَانَ اللَّهُ غَفُورًا رَّحِيمًا} (الفرقان: 70)

Allah the Almighty says: {Except those who repent and believe (in Islamic Monotheism), and do righteous deeds, for those, Allah will change their sins into good deeds and Allah is Oft-Forgiving, Most Merciful}. (Al-Furqan, 70)

قال الله تعالى: {وَالَّذِينَ إِذَا فَعَلُوا فَاحِشَةً أَوْ ظَلَمُوا أَنْفُسَهُمْ ذَكَرُوا اللَّهَ فَاسْتَغْفَرُوا لِذُنُوبِهِمْ وَمَنْ يَغْفِرُ الذُّنُوبَ إِلَّا اللَّهُ وَلَمْ يُصِرُّوا عَلَى مَا فَعَلُوا وَهُمْ يَعْلَمُونَ * أُولَٰئِكَ جَزَاؤُهُمْ مَغْفِرَةٌ مِنْ رَبِّهِمْ وَجَنَّاتٌ تَجْرِي مِنْ تَحْتِهَا الْأَنْهَارُ خَالِدِينَ فِيهَا وَنِعْمَ أَجْرُ الْعَامِلِينَ} [آل عمران: 135، 136]

Allah the Almighty says: {And those who, when they have committed Fahishah (illegal sexual intercourse) or wronged themselves with evil, remember Allah and ask forgiveness for their sins; -and none can forgive sins but Allah - and do not persist in what (wrong) they have done, while they know. For such, the reward is Forgiveness from their Lord, and Gardens with rivers flowing underneath (Paradise), wherein they shall abide forever. How excellent is this reward for the doers (who do righteous deeds according to Allah's Orders)}. (Al' Imran, 135, 136)

قال رسول الله ﷺ: "التوبة تهدم ما قبلها من الخطايا". وعن عبد الله بن مسعود رضي الله عنه قال: سمعت رسول الله ﷺ يقول: "لَلهُ أشد فرحًا بتوبة عبده المؤمن من رجل في أرض فلاة، معه راحلته، عليها طعامه وشرابه، فنام فاستيقظ وقد ذهبت، فطلبها حتى أدركه العطش، ثم قال: أرجع إلى مكاني الذي كنت فيه فأموت، فرجع إلى مكانه فنام، فاستيقظ فإذا راحلته عنده، عليها طعامه وشرابه"، وفي رواية: "فالله أشد فرحًا بتوبة عبده من هذا براحلته وزاده". [رواه البخاري ومسلم]

Allah's Messenger (Peace be upon him) says: "Repentance demolishes all the previous evil deeds.” 'Abdullah Ibn Mas'ud (May Allah be pleased with him) reported: I heard Allah's Messenger (Peace be upon him) as saying: Allah is more pleased with the repentance of His believing servant than a person who loses his riding beast carrying food and drink. He sleeps (being disappointed of its recovery) and then gets up and goes in search for that, until he is stricken with thirst, then comes back to the place where he had been before and goes to sleep completely exhausted placing his head upon his hands waiting for death. And when he gets up, lol There is before him his riding beast and his provisions of food and drink. Allah is more pleased with the repentance of His servant than the recovery of this riding beast along with the provisions (of food and drink).”(Bukhari and Muslim)
