أَلَمْ تَرَ إِلَى الَّذِينَ نُهُوا عَنِ النَّجْوَىٰ ثُمَّ يَعُودُونَ لِمَا نُهُوا عَنْهُ وَيَتَنَاجَوْنَ بِالْإِثْمِ وَالْعُدْوَانِ وَمَعْصِيَتِ الرَّسُولِ وَإِذَا جَاءُوكَ حَيَّوْكَ بِمَا لَمْ يُحَيِّكَ بِهِ اللَّهُ وَيَقُولُونَ فِي أَنفُسِهِمْ لَوْلَا يُعَذِّبُنَا اللَّهُ بِمَا نَقُولُ ۚ حَسْبُهُمْ جَهَنَّمُ يَصْلَوْنَهَا ۖ فَبِئْسَ الْمَصِيرُ (8)
(58:8) Have you not seen those who were forbidden to whisper and yet they engaged in what they had been forbidden? *21 They secretly converse among themselves concerning sin and transgression and disobedience to the Messenger. And when they come to you, they greet you in a manner that Allah does not greet you, *22 and say to themselves: 'Why does Allah not chastise us for these utterances of ours?' *23 Hell it is that shall suffice them, and in it will they burn. How woeful is their destination!
*21) This shows that before the revelation of this verse the Holy Prophet (upon whom by Allah's peace) had forbidden the people this practice. Yet when they did not desist, AIIah directly sent down this verse containing His warning and wrath for such people.
*22) This was the common practice of the Jews and the hypocrites. According to several traditions, some Jews came before the Holy Prophet (upon be Allah's peace) and said: "As-sam alaika ya abul-Qasim. " That is, they pronounced as-sam `alaika in such a manner as to give the impression that they had said as-salam alaika (peace be on you), which is the Islamic way of greeting. But actually they had said "Sam ", which means death. In response the Holy Prophet said: "wa alaikum. "Hadrat `A'ishah retorted: "May death visit you and the curse of Allah!" The Holy Prophet warned her, saying: " `A'ishah, Allah does not like abusive language," She submitted: "Didn't you hear, O Messenger of Allah what they said?" The Holy Prophet replied: "And didn't you hear what reply I gave? I said: and the same upon you." (Bukhiiri, Muslim, Ibn Jarir Ibn Abi Hatim). Hadrat `Abdullah bin `Abbiis has stated that both the Jews and the hypocrites had adopted this very way of greeting. (Ibn Jarir).
*23) That is, they regarded it as a proof of the Holy Prophet's not being a Messenger. They thought that if he had been a true Messenger, they would be punished by a torment as soon as they greeted him in that way. Since there was not torment while they were greeting him day and night like that, he was not a Messenger of Allah.
