It was reported that the above Ayah is explained by Allah's statement,
﴿قَالاَ رَبَّنَا ظَلَمْنَآ أَنفُسَنَا وَإِن لَّمْ تَغْفِرْ لَنَا وَتَرْحَمْنَا لَنَكُونَنَّ مِنَ الْخَـسِرِينَ ﴾
(They said: "Our Lord! We have wronged ourselves. If You forgive us not, and bestow not upon us Your mercy, we shall certainly be of the losers.'') (7:23) as Mujahid, Sa`id bin Jubayr, Abu Al-`Aliyah, Ar-Rabi` bin Anas, Al-Hasan, Qatadah, Muhammad bin Ka`b Al-Qurazi, Khaلlid bin Ma`dan, `Ata' Al-Khurasani and `Abdur-Rahman bin Zayd bin Aslam have stated. As-Suddi said that Ibn `Abbas commented on,
﴿فَتَلَقَّى ءَادَمُ مِن رَّبِّهِ كَلِمَاتٍ﴾
(Then Adam received from his Lord Words) "Adam said, `O Lord! Did You not created me with Your Own Hands' He said, `Yes.' He said, `And blow life into me' He said, `Yes.' He said, `And when I sneezed, You said, `May Allah grant you His mercy.' Does not Your mercy precede Your anger' He was told, `Yes.' Adam said, `And You destined me to commit this evil act' He was told, `Yes.' He said, `If I repent, will You send me back to Paradise' Allah said, `Yes.''' Similar is reported from Al-`Awfi, Sa`id bin Jubayr, Sa`id bin Ma`bad, and Ibn `Abbas. Al-Hakim recorded this Hadith in his Mustadrak from Ibn Jubayr, who narrated it from Ibn `Abbas. Al-Hakim said, "Its chain is Sahih and they (Al-Bukhari and Muslim) did not record it.''
﴿إِنَّهُ هُوَ التَّوَّابُ الرَّحِيمُ﴾
(Verily, He is the One Who forgives (accepts repentance), the Most Merciful) (2:37) means that Allah forgives whoever regrets his error and returns to Him in repentance. This meaning is similar to Allah's statements,
﴿أَلَمْ يَعْلَمُواْ أَنَّ اللَّهَ هُوَ يَقْبَلُ التَّوْبَةَ عَنْ عِبَادِهِ﴾
(Know they not that Allah accepts repentance from His servants) (9:104),
﴿وَمَن يَعْمَلْ سُوءاً أَوْ يَظْلِمْ نَفْسَهُ﴾
(And whoever does evil or wrongs himself) (4:110) and
﴿وَمَن تَابَ وَعَمِلَ صَـلِحاً﴾
(And whosoever repents and does righteous good deeds) (25:71).
The Ayat mentioned above, testify to the fact that Allah forgives the sins of whoever repents, demonstrating His kindness and mercy towards His creation and servants. There is no deity worthy of worship except Allah, the Most Forgiving, the Most Merciful.
﴿قُلْنَا اهْبِطُواْ مِنْهَا جَمِيعًا فَإِمَّا يَأْتِيَنَّكُم مِّنِّى هُدًى فَمَن تَبِعَ هُدَايَ فَلاَ خَوْفٌ عَلَيْهِمْ وَلاَ هُمْ يَحْزَنُونَ - وَالَّذِينَ كَفَرُواْ وَكَذَّبُواْ بِآيَـتِنَآ أُولَـئِكَ أَصْحَـبُ النَّارِ هُمْ فِيهَا خَـلِدُونَ ﴾
(38. We said: "Get down all of you from this place (the Paradise), then whenever there comes to you Hudan (guidance) from Me, and whoever follows My guidance, there shall be no fear on them, nor shall they grieve.) (39. But those who disbelieve and belie Our Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) ـ such are the dwellers of the Fire. They shall abide therein forever.'')
Allah stated that when He sent Adam, Hawwa', and Shaytan to earth from Paradise, He warned them that He will reveal Books and send Prophets and Messengers to them, i.e., to their offspring. Abu Al-`Aliyah said, "Al-Huda, refers to the Prophets, Messengers, the clear signs and plain explanation.''
﴿فَمَن تَبِعَ هُدَايَ﴾
(And whoever follows My guidance) meaning, whoever accepts what is contained in My Books and what I send the Messengers with,
﴿فَلاَ خَوْفٌ عَلَيْهِمْ﴾
(There shall be no fear on them) regarding the Hereafter,
﴿وَلاَ هُمْ يَحْزَنُونَ﴾
(nor shall they grieve) regarding the life of this world. Similarly, in Surat Ta Ha, Allah said,
﴿قَالَ اهْبِطَا مِنْهَا جَمِيعاً بَعْضُكُمْ لِبَعْضٍ عَدُوٌّ فَإِمَّا يَأْتِيَنَّكُم مِّنِّى هُدًى فَمَنِ اتَّبَعَ هُدَاىَ فَلاَ يَضِلُّ وَلاَ يَشْقَى ﴾
(He (Allah) said: "Get you down (from the Paradise to the earth), both of you, together, some of you are an enemy to some others. Then if there comes to you guidance from Me, then whoever follows My guidance, he shall neither go astray, nor shall he be distressed.) (20:123)
Ibn `Abbas commented, "He will not be misguided in this life or miserable in the Hereafter.'' The Ayah,
﴿وَمَنْ أَعْرَضَ عَن ذِكْرِى فَإِنَّ لَهُ مَعِيشَةً ضَنكاً وَنَحْشُرُهُ يَوْمَ الْقِيـمَةِ أَعْمَى ﴾
(But whosoever turns away from My Reminder (i.e. neither believes in this Qur'an nor acts on its teachings) verily, for him is a life of hardship, and We shall raise him up blind on the Day of Resurrection.) (20:124) is similar to what Allah stated here,
﴿وَالَّذِينَ كَفَرُواْ وَكَذَّبُواْ بِآيَـتِنَآ أُولَـئِكَ أَصْحَـبُ النَّارِ هُمْ فِيهَا خَـلِدُونَ ﴾
(But those who disbelieve and belie Our Ayat ـ such are the dwellers of the Fire. They shall abide therein forever), meaning, they will remain in Hell for eternity and will not find a way out of it.
﴿يَـبَنِى إِسْرَءِيلَ اذْكُرُواْ نِعْمَتِيَ الَّتِى أَنْعَمْتُ عَلَيْكُمْ وَأَوْفُواْ بِعَهْدِى أُوفِ بِعَهْدِكُمْ وَإِيَّـىَ فَارْهَبُونِ - وَءَامِنُواْ بِمَآ أَنزَلْتُ مُصَدِّقًا لِّمَا مَعَكُمْ وَلاَ تَكُونُواْ أَوَّلَ كَافِرٍ بِهِ وَلاَ تَشْتَرُواْ بِآيَـتِي ثَمَنًا قَلِيلاً وَإِيَّـىَ فَاتَّقُونِ ﴾
(40. O Children of Israel! Remember My favor which I bestowed upon you, and fulfill (your obligations to) My covenant (with you) so that I fulfill (My obligations to) your covenant (with Me), and fear none but Me.) (41. And believe in what I have sent down (this Qur'an), confirming that which is with you (the Tawrah and the Injil), and be not the first to disbelieve therein, and buy not with My verses (the Tawrah and the Injil) a small price (i.e. getting a small gain by selling My verses), and fear Me and Me alone.)
