اقرأ وتدبر الآية 797 من سورة سُورَةُ الأَنۡعَامِ: وَقَالُوا لَوْلَا أُنْزِلَ عَلَيْهِ مَلَكٌ ۖ وَلَوْ أَنْزَلْنَا مَلَكًا لَقُضِيَ الْأَمْرُ ثُمَّ لَا يُنْظَرُونَ
وَقَالُوا لَوْلَا أُنْزِلَ عَلَيْهِ مَلَكٌ ۖ وَلَوْ أَنْزَلْنَا مَلَكًا لَقُضِيَ الْأَمْرُ ثُمَّ لَا يُنْظَرُونَ
They are saying, too, "Why has not an angel (visibly] been sent down unto him?" But had we sent down an angel, all would indeed have been decided, and they would have been allowed no further respite [for repentance.
