Allah tells us about when the angels came to Lut in the form of young men with handsome faces. When they entered his home, he said:

[قَالَ إِنَّكُمْ قَوْمٌ مُّنكَرُونَ - قَالُواْ بَلْ جِئْنَـكَ بِمَا كَانُواْ فِيهِ يَمْتَرُونَ ]

("Verily, you are people unknown to me.'' They said: "Nay, we have come to you with that (torment) which they have been doubting.'') meaning that they were bringing the punishment and destruction that the people doubted they would ever suffer from.

[وَآتَيْنَـكَ بِالْحَقِّ]

(And we have brought you the truth) is like the Ayah,

[مَا نُنَزِّلُ الْمَلَـئِكَةَ إِلاَّ بِالحَقِّ]

(We do not send the angels down except with the truth) [15:8] and

[وِإِنَّا لَصَـدِقُونَ]

(and certainly, we tell the truth.) They said this in affirmation of the news that they brought him, that he would be saved and his people would be destroyed.

[فَأَسْرِ بِأَهْلِكَ بِقِطْعٍ مِّنَ الَّيْلِ وَاتَّبِعْ أَدْبَـرَهُمْ وَلاَ يَلْتَفِتْ مِنكُمْ أَحَدٌ وَامْضُواْ حَيْثُ تُؤْمَرُونَ - وَقَضَيْنَآ إِلَيْهِ ذَلِكَ الاٌّمْرَ أَنَّ دَابِرَ هَـؤُلآْءِ مَقْطُوعٌ مُّصْبِحِينَ ]

, (65. "Then travel for a portion of the night with your family, and you go behind them in the rear, and let no one amongst you look back, but go on to where you are ordered.'') (66. And We made this decree known to him that those (sinners) would be rooted out in the early morning.)
