﴿ إِذْ جَآءَتْهُمُ ٱلرُّسُلُ مِنۢ بَيْنِ أَيْدِيهِمْ وَمِنْ خَلْفِهِمْ أَلَّا تَعْبُدُوٓا۟ إِلَّا ٱللَّهَ ۖ قَالُوا۟ لَوْ شَآءَ رَبُّنَا لَأَنزَلَ مَلَٰٓئِكَةًۭ فَإِنَّا بِمَآ أُرْسِلْتُم بِهِۦ كَٰفِرُونَ ﴾

“Lo! There came unto them [God’s] apostles, speaking of what lay open before them and what was [still] beyond their ken, [and calling unto them,] “Worship none but God!” They answered: “If our Sustainer had willed [us to believe in what you say], He would have sent down angels [as His message-bearers]. As it is, behold, we deny that there is any truth in what you [claim to] have been sent with!””

When the messengers came to them from in front of them and from behind them that is coming to them to warn them and leaving them behind as they departed but they disbelieved as will be stated shortly — the destruction of them meant would only take place in his time — saying ‘Worship none but God’ they said ‘Had our Lord willed He would have surely sent down to us angels; therefore we indeed disbelieve in what you according to your claim have been sent with!’
