Commentary
In the verse يَا عِيسَىٰ إِنِّي مُتَوَفِّيكَ وَرَافِعُكَ (Isa, I am to take you in full and lift you towards Me... 3:55) appearing in Surah 'Al-` Imran, Almighty Allah had made five promises in connection with foiling the Jewish plans against Sayyidna ` Isa (علیہ السلام) and protecting him from their hostile intentions. A detailed explanation of these has been given earlier on that occasion in Surah 'Al-` Imran. One of the promises made there was that the Jews will not be allowed to have their way with their intention to kill Sayyidna ` Isa (علیہ السلام) . Instead of that, Allah will lift him towards Him.
In the present verses (157-158) of Surah al-Nis-a', it has been made explicit that they did not kill nor crucify Sayyidna ` Isa (علیہ السلام) ، rather, what actually happened was that they were deluded by resemblance.
How were the Jews 'deluded by resemblance?'
While explaining the words of the Qur'an: وَلَـٰكِن شُبِّهَ لَهُمْ (but they were deluded by resemblance), master exegete, Dahhak says: It so transpired that, following the intention of Jews to kill Sayyidna ` Isa (علیہ السلام) his disciples assembled at a given place. Sayyidna ` Isa (علیہ السلام) joined them there. It was Iblis who gave the address of Sayyidna ` Isa (علیہ السلام) to the execution squad standing ready for the mission. Four thousand men surrounded the suspected house. Sayyidna ` Isa (علیہ السلام) said to his disciples : 'Is one of you willing to go out and be killed and then be in Paradise with me?' One of them offered to do so. Sayyidna ` Isa (علیہ السلام) gave him his shirt and head-cover. Then, cast on him was the resemblance of Jesus and as soon as he came out, the Jews, believing him to be Jesus, caught him and crucified him, and Sayyidna ` Isa was lifted. (Qurtubi)
According to some reports, the Jews had sent a person known to Arabs as Teetlanoos to kill Sayyidna ` Isa (علیہ السلام) . He did not find Sayyidna ` Isa (علیہ السلام) in the house for he was already lifted by Allah towards Himself. So, when this person came out of the house, he had been made to resemble the looks of Sayyidna ` Isa . The Jews took him to be Sayyidna ` Isa (علیہ السلام) . Thus, they took away their own man and killed him. (Mazhari)
There is room for whichever of the situations came to pass - the Holy Qur'an has not determined any particular situation. Therefore, Allah alone knows what really happened. However, this sentence of the Holy Qur'an seen with other exegetical reports does yield the common factor that the Jews and Christians were subjected to compelling delusion. The event as it took shape remained hidden from them, though they did advance all sorts of claims based on their conjectures which only landed them into mutual differences. This is what the Holy Qur'an points out to in the following words:
وَإِنَّ الَّذِينَ اخْتَلَفُوا فِيهِ لَفِي شَكٍّ مِّنْهُ ۚ مَا لَهُم بِهِ مِنْ عِلْمٍ إِلَّا اتِّبَاعَ الظَّنِّ ۚ وَمَا قَتَلُوهُ يَقِينًا ﴿157﴾
And those who disputed in this matter are certainly in doubt about it. They have no knowledge of it, but they follow whims.
It means that they do not have certitude based on any true knowledge. The diverse claims put forward by those who have differed in the case of Masih (علیہ السلام) are simply based on doubt and conjecture. The truth of the matter is that they certainly did not kill Masih (علیہ السلام) rather Allah lifted him towards Himself.
According to some other reports, when some of them woke up to what had happened, they said, We seem to have killed our own man, for the man we have put to death resembles Masih in face only but not in the rest of the body. Now, if this man we have killed is Masih (علیہ السلام) where, then, is our man? And if this is our man where, then, is Masih (علیہ السلام) ?'
Verse 158, part of which was referred to immediately earlier, ends at: وَكَانَ اللَّـهُ عَزِيزًا حَكِيمًا : (And Allah is All-Mighty, All-Wise) carrying a significant message. It means that the planning of Jews to kill Sayyidna ` Isa (علیہ السلام) was insignificant as matched against the Power of Allah who has taken it upon Himself to protect Sayyidna ` Isa (علیہ السلام) . Might and mastery are His domain. If materialists in their single-track isolation, remain incapable of understanding the reality of the 'lifting off of Sayyidna ` Isa (علیہ السلام) ، that is their own limitation. As for Allah, He is All-Wise - everything He does is based on wisdom and fitness to whatever end is desired.
