Sorcery is a fact:
Sorcery is a fact which cannot be falsified. In the Quran Allah tells about the sorcerers of the Pharaoh in these words:
قَالَ أَلْقُوا فَلَمَّا أَلْقَوْا سَحَرُوا أَعْيُنَ النَّاسِ وَاسْتَرْهَبُوهُمْ وَجَاءُوا بِسِحْرٍ عَظِيمٍ (116) (الأعراف : 116)
(Translation of meaning) “He [Pharaoh] said: Throw! And when they threw they cast a spell upon the people’s eyes, and overawed them, and produced a mighty spell” (Al-A’raf: 116). In another place He said:
وَاتَّبَعُوا مَا تَتْلُو الشَّيَاطِينُ عَلَى مُلْكِ سُلَيْمَانَ وَمَا كَفَرَ سُلَيْمَانُ وَلَكِنَّ الشَّيَاطِينَ كَفَرُوا يُعَلِّمُونَ النَّاسَ السِّحْرَ (102) (البقرة: 102)
(Translation of meaning) “And follow that which the devils falsely related against the kingdom of Solomon. Solomon disbelieved not; but the devils disbelieved, teaching mankind magic” (Al-Baqarah: 102).
Allah’s Messenger) sallAllahu ‘alayhi wa sallam) himself became a victim of evil spell. According to a narration by Hadrat Ayesha (RadhiAllahu Anha), a Jew named Labeed Bin al-A’sam, who belonged to the Bani Zuraiq tribe once, cast a spell upon the Prophet (sallAllahu ‘alayhi wa sallam).
Its effect was that the Prophet (sallAllahu ‘alayhi wa sallam) imagined that he had done something which he had in fact not done. One day he made a supplication to Allah Ta’ala and then said my prayer has been granted. Then came two persons to me one of whom sat to my head and the other to my legs. One asked the other what he is suffering from. The other replied an evil spell has been cast upon him. The first one then asked who has done this. The other one replied Labeed Bin al-A’sam. On what object this spell has been cast? The other replied on the hair of head which fell while combing and on the blossoms of the male palm-date tree. Then the first one asked at which place? The other one replied at a well named Dhi Zarwan. The Prophet (sallAllahu ‘alayhi wa sallam) then went to that well. Coming back he told Ayesha (RadhiAllahu Anha) that it appeared as if they were the heads of devils (condensed narrative/Al-Bukhari and Muslim). As a matter of fact, a Muslim should always pray to his God, beseech for His forgiveness and seek his refuge against the evil of the devils. Allah has ordained:
وَقُلْ رَبِّ أَعُوذُ بِكَ مِنْ هَمَزَاتِ الشَّيَاطِينِ (97) وَأَعُوذُ بِكَ رَبِّ أَنْ يَحْضُرُونِ(98) (المؤمنون :97 – 98)
(Translation of meaning) “And say: My Lord! I seek refuge in Thee from suggestions of the evil ones; and I seek refuge in Thee, my Lord, lest they be present with me” (Al-Mominoon: 97-98). Allah has Himself guaranteed that
إِنَّ عِبَادِي لَيْسَ لَكَ عَلَيْهِمْ سُلْطَانٌ إِلاَّ مَنْ اتَّبَعَكَ مِنْ الْغَاوِينَ (42) (الحجر : 42)
(Translation of meaning) “Lo! As for My slaves, thou hast no power over any of them save the deviant ones as follow thee” (Al-Hijr: 42).
Thus about Hadrat Umar Bin al-Khattab (RadhiAllahu Anhu) it is reported that whichever, path, he took Satan moved away from it because he was a sincere follower of Allah.
About the jinns it should be understood that by themselves they have no power over anything unless willed by Allah, and likewise they have no knowledge of the occult [ghaib]. Allah declares:
عَالِمُ الْغَيْبِ فَلا يُظْهِرُ عَلَى غَيْبِهِ أَحَداً (26) إِلاَّ مَنْ ارْتَضَى مِنْ رَسُولٍ فَإِنَّهُ يَسْلُكُ مِنْ بَيْنِ يَدَيْهِ وَمِنْ خَلْفِهِ رَصَداً (27) (الجن : 26 – 27)
(Translation of meaning) “[Allah] is the knower of the unseen, and He revealeth unto none His secret, Save unto every messenger whom He hath chosen, and then He maketh a guard before him and a guard behind him” (Al-Jinn: 26-27).
Certainly, Allah the Almighty alone is our protector against the devils and evil forces. One who takes refuge in Allah is safe from all evil-doings of the devils. He is the best helper and corrector of all the wrongs. Iblis became a victim of his arrogance. When Allah commanded him to prostrate before Adam, he said:
قَالَ مَا مَنَعَكَ أَلَّا تَسْجُدَ إِذْ أَمَرْتُكَ ۖ قَالَ أَنَا خَيْرٌ مِنْهُ خَلَقْتَنِي مِنْ نَارٍ وَخَلَقْتَهُ مِنْ طِينٍ (الأعراف : 12)
(Translation of meaning) “He said: What hindered thee that thou didst not fall prostrate when I bade thee? (Iblis) said: I am better than him. Thou createdst me of fire while him Thou didst create of mud.” (Al-A’raf: 12).
Allah the Almighty became very angry over his defiance and ordered him to get out of Paradise:
قَالَ اخْرُجْ مِنْهَا مَذْءُوماً مَدْحُوراً لَمَنْ تَبِعَكَ مِنْهُمْ لأَمْلأَنَّ جَهَنَّمَ مِنْكُمْ أَجْمَعِينَ (18) (الأعراف : 18)
(Translation of meaning) “[Allah] said: Go forth from hence, degraded, banished. As for such of them as follow thee, surely I will fill hell with all of you” (Al-A’raf: 18).
Like human beings the jinns are also bound to obey and worship Allah. This is proved from various verses of the holy Quran and the sayings of the Prophet (sallAllahu ‘alayhi wa sallam).
Once Allah’s Messenger) sallAllahu ‘alayhi wa sallam) came to a gathering of his Companions and recited Surah Rahman from the beginning to the end. The Companion listened to him solemnly. Then the Prophet (sallAllahu ‘alayhi wa sallam) explained that he recited this Surah before the jinns who made the best possible response to it. When I recited this verse فَبِأَيِّ آلاءِ رَبِّكُمَا تُكَذِّبَانِ “Then which of the bounties of your Creator will you refute?” They replied «لاَ بِشَىْءٍ مِنْ نِعَمِكَ رَبَّنَا نُكَذِّبُ فَلَكَ الْحَمْدُ»”none of Your bounties we refute; all praise is for You” (Tirmidhi).
Iblis knew very well that he was a creature of Allah and that he was bound to obey and worship Him but out of arrogance he defied the command of Allah. But an obedient Muslim cannot defy the commands of Allah. On the Day of Judgment people will see a man lodged in Hell. Then out of curiosity they will ask him that in the world you ordered us to do good and prevented us from doing evil. Now why are you here? He will say yes I ordered you to do good but I myself did not do good; and I prevented you from evil but I myself did not desist from evil. On the Day of Judgment the treatment of Satan will be curious. He himself will disown all his accomplices and collaborators. Allah proclaims:
وَقَالَ الشَّيْطَانُ لَمَّا قُضِيَ الأَمْرُ إِنَّ اللَّهَ وَعَدَكُمْ وَعْدَ الْحَقِّ وَوَعَدْتُكُمْ فَأَخْلَفْتُكُمْ وَمَا كَانَ لِي عَلَيْكُمْ مِنْ سُلْطَانٍ إِلاَّ أَنْ دَعَوْتُكُمْ فَاسْتَجَبْتُمْ لِي فَلا تَلُومُونِي وَلُومُوا أَنْفُسَكُمْ (22) (إبراهيم :22)
(Translation of meaning) [“And Satan saith, when the matter has been decided: Lo! Allah promised you a promise of truth; and I promised you, then failed you; And I had no power over you save that I called unto you and ye obeyed me. So blame me not, but blame yourselves. I cannot help you, nor can ye help me. Lo! I disbelieved in that which ye before ascribed to me, Lo! For wrong-doers is a painful doom”(Ibrahim: 22)].
Some people deny the existence of the jinn. They have no reason for their denial except that they do not see such a creature in material form or perceive it with their senses. This is in fact not a matter of the sensory world but a matter of belief in the Unseen [ghaib]. Can these people deny the existence of such forces as the electrical current or gravity or human soul which are not visible? As a matter of fact, they admit the existence of all these forces. Then why can’t they believe in the existence of jinns when God Almighty himself has revealed that He has created the jinn like the human species and all of them are enjoined to serve and obey Him. Belief in the Unseen is one of the tenets of Islam. If one believes in the Unseen then it is enough to believe in the existence of the Jinni species because the Book of Allah [Quran] contains a full Surah with the title of “Al-Jinn”.
