قُلۡنَا ٱهۡبِطُواْ مِنۡهَا جَمِيعٗاۖ فَإِمَّا يَأۡتِيَنَّكُم مِّنِّي هُدٗى فَمَن تَبِعَ هُدَايَ فَلَا خَوۡفٌ عَلَيۡهِمۡ وَلَا هُمۡ يَحۡزَنُونَ
We said, “Go down from Paradise, all of you; then if some guidance comes to you from Me – so whoever follows My guidance, for such is neither fear nor any grief.”
Tafsir:
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.
