كَمَثَلِ الشَّيْطَانِ إِذْ قَالَ لِلْإِنسَانِ اكْفُرْ (The example [ of the hypocrites ] is like the Shaitan when he says to a human being, "Become a disbeliever" then once he disbelieves, he says, "I disown you; I fear Allah, the Lord of the worlds."....59:16) This is another example of the hypocrites who made false promises of solidarity and support to the Banu Nadir, and provoked the latter to fight against the Messenger of Allah ﷺ . But when the Muslims besieged them, not a single hypocrite came forward to assist. The Qur'an here uses a simile to illustrate the similarity between a hypocrite and the Shaitan. The Shaitan incited man to disbelieve and promised him the world, but when he was seriously involved in disbelief, he said that he has nothing to do with him. Only Allah knows how many such episodes the devil must have been involved in, textually, however, we find one such episode narrated in the Qur'an in Surah Anfal, verse [ 48]:
وَإِذْ زَيَّنَ لَهُمُ الشَّيْطَانُ أَعْمَالَهُمْ وَقَالَ لَا غَالِبَ لَكُمُ الْيَوْمَ مِنَ النَّاسِ وَإِنِّي جَارٌ لَّكُمْ ۖ فَلَمَّا تَرَاءَتِ الْفِئَتَانِ نَكَصَ عَلَىٰ عَقِبَيْهِ وَقَالَ إِنِّي بَرِيءٌ مِّنكُمْ إِنِّي أَرَىٰ مَا لَا تَرَوْنَ إِنِّي أَخَافُ اللَّـهَ ۚ وَاللَّـهُ شَدِيدُ الْعِقَابِ
"And when the Shaitan beautified their deeds for them and said, 'None of the people is to overpower you today, and I am a protector for you.' But, when the two groups saw each other, he turned back on his heels and said, 'I have nothing to do with you. I am seeing what you do not see. I am scared of Allah, and Allah is severe in punishment.'
This incident occurred on the occasion of the battle of Badr when the Shaitan misled the pagan Quraish, urged them to wage a war against Muslims, and then he withdrew, and left them in the lurch when they were in the middle of a pitched-battle. It is not clear how the Shaitan did all this, whether he cast suggestions into their minds or whether he came to them in human shape and spoke to them face to face. A full explanation is available in Volume [ 4] of Ma’ ariful Qur’ an, pages 242-247.
If the verse refers to this incident, in which the Shaitan provokes man to disbelieve and when he does that, he washes his hands of them, it does not seem that the Shaitan asked them to commit kufr, because they were already kafirs. He asked them to be firm in opposing the Messenger ﷺ . The answer is all too obvious, in that it is all the same whether he asked them to commit kufr, or bids them to remain firm in their kufr or fight the Messenger of Allah ﷺ ، because it is also tantamount to kufr.
Tafsir Mazhari, Qurtubi, Ibn Kathir and others have cited several incidents where monks and devotees were deceived into kufr. For example, one of the Israeli monks devoted himself to Allah in his synagogue, and fasted consecutively and broke his fast only once in ten days. In this way, he spent seventy years of his life. The accursed Shaitan pursued him. He sent after him the most cunning devil in the shape of a monk, a devotee of God. He went up to him and exerted himself in the worship of God and thus built up confidence in the genuine monk. Eventually, the impostor succeeded in teaching the monk a few of the prayers that are efficacious in curing the sickly people. Then the former exerted his influence on many people to fall sick, and gave them the monk's address. When the latter recited the prayers, the devil would remove his influence and thus they would feel cured. He kept up this process for a long period of time, until one day he performed his exertion on the beautiful daughter of an Israeli leader. He sent her also to the monk. He succeeded in getting her into his synagogue and gradually he succeeded in getting him to commit fornication with the girl who, as a result, fell pregnant. He suggested that the girl be killed to save face. After the killing, the devil himself went around telling the story of the killing and put up the people against the monk. They, in their fury, demolished the synagogue and decided to kill him and crucify him. Then the Shaitan went back to the monk and said to him that there is no way out to save his life. 'Of course', he said to him, 'there is one way of saving your life, in that you prostrate to me and I will save your life.' The monk had already committed all the sins. The way to commit kufr was paved. So, he prostrated. At that juncture, the Shaitan said to him plainly, 'You were not falling into my trap. I adopted all these guiles for you to commit kufr. I cannot assist you in any way.' This story is recounted fully in Tafsir Mazhari and Qurtubi. Allah, the Pure and Exalted, knows best!
