وَقَالُواْ لَوْلا أُنزِلَ عَلَيْهِ مَلَكٌAnd they say:"Why has not an angel been sent down to him!"to convey the Message with admonition along with him.Allah replied,وَلَوْ أَنزَلْنَا مَلَكًا لَّقُضِيَ الامْرُ ثُمَّ لَا يُنظَرُونَHad We sent down an angel, the matter would have been judged at once, and no respite would be granted to them.Consequently, even if the angels descend, while the disbelievers still had the same attitude, then the torment will surely befall them from Allah as a consequence.Allah said in other Ayat,مَا نُنَزِّلُ الْمَلَـيِكَةَ إِلاَّ بِالحَقِّ وَمَا كَانُواْ إِذًا مُّنظَرِينَWe send not the angels down except with the truth (i.e. for torment, etc.), and in that case, they (the disbelievers) would have no respite! (15:8)and,يَوْمَ يَرَوْنَ الْمَلَـيِكَةَ لَا بُشْرَى يَوْمَيِذٍ لِّلْمُجْرِمِينَOn the Day they will see the angels, no glad tidings will there be for the criminals that day. (25:22)Allah's statement,وَلَوْ جَعَلْنَاهُ مَلَكًا لَّجَعَلْنَاهُ رَجُلً وَلَلَبَسْنَا عَلَيْهِم مَّا يَلْبِسُونَ
