Allah emphasizes His generosity and kindness, in that He forgives whoever repents to Him from whatever evil they commit. Allah said,

﴿وَمَن يَعْمَلْ سُوءاً أَوْ يَظْلِمْ نَفْسَهُ ثُمَّ يَسْتَغْفِرِ اللَّهَ يَجِدِ اللَّهَ غَفُوراً رَّحِيماً ﴾

(And whoever does evil or wrongs himself but afterwards seeks Allah's forgiveness, he will find Allah Oft-Forgiving, Most Merciful.) `Ali bin Abi Talhah said that Ibn `Abbas commented about this Ayah, "Allah informs His servants of His forgiveness, forbearing generosity and expansive mercy. So whoever commits a sin, whether minor or major,

﴿ثُمَّ يَسْتَغْفِرِ اللَّهَ يَجِدِ اللَّهَ غَفُوراً رَّحِيماً﴾

(but afterwards seeks Allah's forgiveness, he will find Allah Oft-Forgiving, Most Merciful.) even if his sins were greater than the heavens, the earth and the mountains.'' Imam Ahmad recorded that `Ali said, "Whenever I hear anything from the Messenger of Allah, Allah benefits me with whatever He wills of that. Abu Bakr told me, and Abu Bakr has said the truth, that the Messenger of Allah said,

«مَا مِنْ مُسْلِمٍ يُذْنِبُ ذَنْبًا، ثُمَّ يَتَوَضَّأُ فَيُصَلِّي رَكْعَتَيْنِ، ثُمَّ يَسْتَغْفِرُ اللهَ لِذلِكَ الذَّنْبِ، إِلَّا غَفَرَ لَه»

(No Muslim commits a sin and then performs ablution, prays two Rak`ahs and begs Allah for forgiveness for that sin, but He forgives him.) He then recited these two Ayat,

﴿وَمَن يَعْمَلْ سُوءاً أَوْ يَظْلِمْ نَفْسَهُ﴾

(And whoever does evil or wrongs himself), and,

﴿وَالَّذِينَ إِذَا فَعَلُواْ فَـحِشَةً أَوْ ظَلَمُواْ أَنْفُسَهُمْ﴾

(And those who, when they have committed Fahishah or wronged themselves with evil).'' Allah's statement,

﴿وَمَن يَكْسِبْ إِثْماً فَإِنَّمَا يَكْسِبُهُ عَلَى نَفْسِهِ﴾

(And whoever earns sin, he earns it only against himself.) is similar to His statement,

﴿وَلاَ تَزِرُ وَازِرَةٌ وِزْرَ أُخْرَى﴾

(And no bearer of burdens shall bear the burden of another). So no one will avail anyone else. Rather, every soul, and none else, shall carry its own burden. This is why Allah said,

﴿وَكَانَ اللَّهُ عَلِيماً حَكِيماً﴾

(And Allah is Ever All-Knowing, All-Wise.) meaning, this occurs due to His knowledge, wisdom, fairness and mercy.

﴿وَعَلَّمَكَ مَا لَمْ تَكُنْ تَعْلَمُ﴾

(and taught you that which you knew not.), before this revelation was sent down to you. Similarly, Allah said,

﴿وَكَذَلِكَ أَوْحَيْنَآ إِلَيْكَ رُوحاً مِّنْ أَمْرِنَا مَا كُنتَ تَدْرِى مَا الْكِتَـبُ﴾

(And thus We have sent to you (O Muhammad ) a Ruh (a revelation, and a mercy) of Our command. You knew not what is the Book) until the end of the Surah. Allah said,

﴿وَمَا كُنتَ تَرْجُو أَن يُلْقَى إِلَيْكَ الْكِتَـبُ إِلاَّ رَحْمَةً مِّن رَّبِّكَ﴾

(And you were not expecting that the Book (this Qur'an) would be sent down to you, but it is a mercy from your Lord). So Allah said;

﴿وَكَانَ فَضْلُ اللَّهِ عَلَيْكَ عَظِيماً﴾

(And ever great is the grace of Allah unto you (O Muhammad )).

﴿لاَّ خَيْرَ فِى كَثِيرٍ مِّن نَّجْوَاهُمْ إِلاَّ مَنْ أَمَرَ بِصَدَقَةٍ أَوْ مَعْرُوفٍ أَوْ إِصْلَـحٍ بَيْنَ النَّاسِ وَمَن يَفْعَلْ ذلِكَ ابْتَغَآءَ مَرْضَـتِ اللَّهِ فَسَوْفَ نُؤْتِيهِ أَجْراً عَظِيماً - وَمَن يُشَاقِقِ الرَّسُولَ مِن بَعْدِ مَا تَبَيَّنَ لَهُ الْهُدَى وَيَتَّبِعْ غَيْرَ سَبِيلِ الْمُؤْمِنِينَ نُوَلِّهِ مَا تَوَلَّى وَنُصْلِهِ جَهَنَّمَ وَسَآءَتْ مَصِيراً ﴾

(114. There is no good in most of their secret talks save (in) him who orders Sadaqah, or goodness, or conciliation between mankind; and he who does this, seeking the good pleasure of Allah, We shall give him a great reward. (115. And whoever contradicts and opposes the Messenger after the right path has been shown clearly to him, and follows other than the believers' way, We shall keep him in the path he has chosen, and burn him in Hell what an evil destination!)
