Surah 4. An-Nisaa'
Ayah 116 - 122
116إِنَّ ٱللَّهَ لَا يَغْفِرُ أَن يُشْرَكَ بِهِۦ وَيَغْفِرُ مَا دُونَ ذَٰلِكَ لِمَن يَشَآءُ ۚ وَمَن يُشْرِكْ بِٱللَّهِ فَقَدْ ضَلَّ ضَلَـٰلًۢا بَعِيدًا
117إِن يَدْعُونَ مِن دُونِهِۦٓ إِلَّآ إِنَـٰثًا وَإِن يَدْعُونَ إِلَّا شَيْطَـٰنًا مَّرِيدًا
118لَّعَنَهُ ٱللَّهُ ۘ وَقَالَ لَأَتَّخِذَنَّ مِنْ عِبَادِكَ نَصِيبًا مَّفْرُوضًا
119وَلَأُضِلَّنَّهُمْ وَلَأُمَنِّيَنَّهُمْ وَلَـَٔامُرَنَّهُمْ فَلَيُبَتِّكُنَّ ءَاذَانَ ٱلْأَنْعَـٰمِ وَلَـَٔامُرَنَّهُمْ فَلَيُغَيِّرُنَّ خَلْقَ ٱللَّهِ ۚ وَمَن يَتَّخِذِ ٱلشَّيْطَـٰنَ وَلِيًّا مِّن دُونِ ٱللَّهِ فَقَدْ خَسِرَ خُسْرَانًا مُّبِينًا
120يَعِدُهُمْ وَيُمَنِّيهِمْ ۖ وَمَا يَعِدُهُمُ ٱلشَّيْطَـٰنُ إِلَّا غُرُورًا
121أُو۟لَـٰٓئِكَ مَأْوَىٰهُمْ جَهَنَّمُ وَلَا يَجِدُونَ عَنْهَا مَحِيصًا
122وَٱلَّذِينَ ءَامَنُوا۟ وَعَمِلُوا۟ ٱلصَّـٰلِحَـٰتِ سَنُدْخِلُهُمْ جَنَّـٰتٍ تَجْرِى مِن تَحْتِهَا ٱلْأَنْهَـٰرُ خَـٰلِدِينَ فِيهَآ أَبَدًا ۖ وَعْدَ ٱللَّهِ حَقًّا ۚ وَمَنْ أَصْدَقُ مِنَ ٱللَّهِ قِيلًا
[116-122] Shirk144 is the only sin that Allah does. not forgive. He may forgive whomever He will, other than this sin, for whoever associates partners with Allah does, in fact, go far astray into deviation. The mushriks invoke to goddesses instead of Allah: they invoke that rebellious Satan,145 on whom Allah has laid His curse; (they obey that Satan) who said to Allah, "I will most surely take due share from your servants146 and will mislead them; I will entice them by vain desires; I will command them and they will slit147 the ears of the cattle by my order, and I will command them and they will make alterations and corrupt Allah's creation."148 Therefore whoever makes this same Satan his patron, instead of God, becomes a manifest loser. Though he makes (false) promises with people and entices them by vain hopes149 all his promises are nothing but deception. The abode of such people is Hell from where they will find no way of escape. As regards those, who believe and do good deeds, We will admit them into Gardens underneath which canals flow, wherein they will abide for ever. This promise of Allah is true and who can be truer in his word than Allah?
144In continuation of the foregoing theme, it has been stated that the hypocrite, who had in his anger gone to the side of the mushriks, did not fully realize the consequences of his foolish action. For this purpose, evils of the way he adopted and the nature of the fellows he accompanied have been pointed out.
145Though none worships Satan by performing devotional ceremonies before him, the one who surrenders oneself entirely to him and follows him wherever he misleads, does act like a devotee of Satan. This also makes it plain that one who obeys any other blindly, in fact, worships him.
146That is, "I will mark off for myself a portion of their time, their labor and their efforts, their energies and their abilities, their wealth and their offspring, and will entice them by deception so that they will devote the major portion of these in my way."
147This alludes to one of the superstitious customs of the pagan Arabs. After a she-camel had given birth to five or ten young ones, they would slit her ears and dedicate her to their god and consider it unlawful to get any work from her. Likewise, if a camel had been a partner in the birth of ten young ones, his ears were also slit to mark that he had been dedicated to a god.
148This does not condemn the alterations that man makes in the creation of God for their right and proper use, for in that case the whole of human civilization will stand condemned as a seduction of Satan. It is obvious that the civilization is nothing but the right and proper use of the things created by God. What the Qur'an describes as devilish alterations is to make wrong and improper use of things against human nature and against their natural functions. Hence, all those forms that are adopted as an escape from the designs of Nature are the results of the enticement of Satan e.g. sodomy, birth control, asceticism, etc. It is equally devilish that females should be made to give up their proper functions and to perform those duties which nature has assigned to males. Instances can be multiplied to show that the disciples of Satan consider the laws of the Creator of the Universe wrong and, therefore, are trying to "reform" them.
149The success of Satan depends entirely upon false promises and deceit In order to mislead individuals and communities, he presents very rosy pictures of his wrong ways to re-assure his victims. He tempts one by holding out the promise of pleasure and success. He allures some by giving the surety of national power and prosperity, while he deludes others by the prospect of the welfare of humanity. and deceives still others by telling them that his is the right way of arriving at the Truth. He also entices some by assuring them that there is no God and Hereafter and that life ends with death and others by giving them a guarantee that they would escape the consequences in the Hereafter, if there is Hereafter by the intercession of this or that saint.
