Allaah (The Most High) said:
وَإِذْ قُلْنَا لِلْمَلَائِكَةِ اسْجُدُوا لِآدَمَ فَسَجَدُوا إِلَّا إِبْلِيسَ كَانَ مِنَ الْجِنِّ فَفَسَقَ عَنْ أَمْرِ رَبِّهِ ۗ أَفَتَتَّخِذُونَهُ وَذُرِّيَّتَهُ أَوْلِيَاءَ مِن دُونِي وَهُمْ لَكُمْ عَدُوٌّ ۚ بِئْسَ لِلظَّالِمِينَ بَدَلًا
And (remember) when We said to the angels; “Prostrate to Adam.” So they prostrated except Iblis (Satan). He was one of the jinns; he disobeyed the Command of his Lord. Will you then take him (Iblis) and his offspring as protectors and helpers rather than Me while they are enemies to you? What an evil is the exchange for the Zalimun (polytheists, and wrong-doers, etc). [18:50]
Imaam Ibnul Qayyim (rahimahullaah) stated:
Allaah says to His slaves: I ennobled your father; raised his rank and gave him preference over others. I commanded all the angels to prostrate to him as a (sign) of honour and nobility, and they obeyed Me; but my enemy and yours (i.e. Iblees) refused (to prostrate) and disobeyed my command. He (Iblees) refrained from obeying Me (Allaah), so how can it be fair seeming to you (sons of Aadam) that you take him and his offspring as allies besides Me (Allaah)- obeying him and disobeying Me; allying with him against what pleases Me, whilst they (Iblees and his offspring) are the severest enemies to you. So you ally with My enemy and he commands you with his enmity. Whoever allies with an enemy of a king, then he is the same as the enemy of the king, for indeed love and obedience cannot be complete except by way of having enmity towards the enemy of the one you follow and having allegiance to the friends of the one you follow. As for having allegiance to the enemy of the king and then claiming that you are the ally of the king, this is impossible…..[End of quote. Source: Al-Jawaab al-Kaafi…118-119]
We ask Allaah (Our Protector) to protect us from having any allegiance to Shaytaan, his offspring and human allies. Indeed, we are constantly in need of repentance due to our shorting comings, so let us always ask Allaah (The Most High) to enable us to turn to Him in repentance and that we never despair of His Mercy. Allaah (The Most High) said:
قُلْ يَا عِبَادِيَ الَّذِينَ أَسْرَفُوا عَلَىٰ أَنفُسِهِمْ لَا تَقْنَطُوا مِن رَّحْمَةِ اللَّهِ ۚ إِنَّ اللَّهَ يَغْفِرُ الذُّنُوبَ جَمِيعًا ۚ إِنَّهُ هُوَ الْغَفُورُ الرَّحِيمُ
Say: “O ‘Ibadi (My slaves) who have transgressed against themselves (by committing evil deeds and sins)! Despair not of the Mercy of Allah, verily Allah forgives all sins. Truly, He is Oft-Forgiving, Most Merciful.
وَأَنِيبُوا إِلَىٰ رَبِّكُمْ وَأَسْلِمُوا لَهُ مِن قَبْلِ أَن يَأْتِيَكُمُ الْعَذَابُ ثُمَّ لَا تُنصَرُونَ
“And turn in repentance and in obedience with true Faith (Islamic Monotheism) to your Lord and submit to Him, (in Islam), before the torment comes upon you, then you will not be helped.
وَاتَّبِعُوا أَحْسَنَ مَا أُنزِلَ إِلَيْكُم مِّن رَّبِّكُم مِّن قَبْلِ أَن يَأْتِيَكُمُ الْعَذَابُ بَغْتَةً وَأَنتُمْ لَا تَشْعُرُونَ
“And follow the best of that which is sent down to you from your Lord (i.e. this Qur’an, do what it orders you to do and keep away from what it forbids), before the torment comes on you suddenly while you perceive not!
أَن تَقُولَ نَفْسٌ يَا حَسْرَتَا عَلَىٰ مَا فَرَّطتُ فِي جَنبِ اللَّهِ وَإِن كُنتُ لَمِنَ السَّاخِرِينَ
Lest a person should say: “Alas, my grief that I was undutiful to Allah (i.e. I have not done what Allah has ordered me to do), and I was indeed among those who mocked [at the truth! i.e. La ilaha ill-Allah (none has the right to be worshipped but Allah), the Qur’an, and Muhammad and at the faithful believers, etc.]
أَوْ تَقُولَ لَوْ أَنَّ اللَّهَ هَدَانِي لَكُنتُ مِنَ الْمُتَّقِينَ
Or (lest) he should say: “If only Allah had guided me, I should indeed have been among the Muttaqun (pious and righteous persons – see V.2:2).”
أَوْ تَقُولَ حِينَ تَرَى الْعَذَابَ لَوْ أَنَّ لِي كَرَّةً فَأَكُونَ مِنَ الْمُحْسِنِينَ
Or (lest) he should say when he sees the torment: “If only I had another chance (to return to the world) then I should indeed be among theMuhsinun (good-doers – see V.2:112).”
بَلَىٰ قَدْ جَاءَتْكَ آيَاتِي فَكَذَّبْتَ بِهَا وَاسْتَكْبَرْتَ وَكُنتَ مِنَ الْكَافِرِينَ
Yes! Verily, there came to you My Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) and you denied them, and were proud and were among the disbelievers.
[Soorah Az-Zumar Aayaat 53-59]
