On the Day they will see the angels -- no good news will there be for the criminals that day. And they will say;"Hijran Mahjura."
means, when they do see the angels, it will not be a good day for them, for on that day there will be no good news for them.
This is also confirmed at the time when they are dying, when the angels bring them the tidings of Hell and the wrath of the Compeller, and when the disbeliever's soul is being taken out, the angels say to it,
"Come out, O evil soul from an evil body, come out to fierce hot wind and boiling water, and the shadow of black smoke."
It refuses to come out and it scatters throughout his body, so they beat him, as Allah says;
وَلَوْ تَرَى إِذْ يَتَوَفَّى الَّذِينَ كَفَرُواْ الْمَلَـيِكَةُ يَضْرِبُونَ وُجُوهَهُمْ وَأَدْبَـرَهُمْ
And if you could see when the angels take away the souls of those who disbelieve; they smite their faces and their backs..." (8;50)
وَلَوْ تَرَى إِذِ الظَّالِمُونَ فِي غَمَرَاتِ الْمَوْتِ وَالْمَليِكَةُ بَاسِطُواْ أَيْدِيهِمْ
And if you could but see when the wrongdoers are in the agonies of death, while the angels are stretching forth their hands.
that is, to beat them;
أَخْرِجُواْ أَنفُسَكُمُ الْيَوْمَ تُجْزَوْنَ عَذَابَ الْهُونِ بِمَا كُنتُمْ تَقُولُونَ عَلَى اللّهِ غَيْرَ الْحَقِّ وَكُنتُمْ عَنْ ايَاتِهِ تَسْتَكْبِرُونَ
(saying);"Deliver your souls! This day you shall be recompensed with the torment of degradation because of what you used to utter against Allah other than the truth. And you used to reject His Ayat with disrespect!" (6;93)
Hence in this Ayah Allah says;
يَوْمَ يَرَوْنَ الْمَلَيِكَةَ لَا بُشْرَى يَوْمَيِذٍ لِّلْمُجْرِمِينَ
On the Day they will see the angels -- no good news will there be for the criminals,
This is in contrast to the state of the believers when death approaches them, for they are given glad tidings of joy and delight.
Allah says;
إِنَّ الَّذِينَ قَالُواْ رَبُّنَا اللَّهُ ثُمَّ اسْتَقَـمُواْ تَتَنَزَّلُ عَلَيْهِمُ الْمَلَـيِكَةُ أَلاَّ تَخَافُواْ وَلَا تَحْزَنُواْ وَأَبْشِرُواْ بِالْجَنَّةِ الَّتِى كُنتُمْ تُوعَدُونَ
نَحْنُ أَوْلِيَأوُكُمْ فِى الْحَيَوةِ الدُّنْيَا وَفِى الاٌّخِرَةِ وَلَكُمْ فِيهَا مَا تَشْتَهِى أَنفُسُكُمْ وَلَكُمْ فِيهَا مَا تَدَّعُونَ
نُزُلاً مِّنْ غَفُورٍ رَّحِيمٍ
Verily, those who say;"Our Lord is Allah," and then they stand firm, on them the angels will descend (saying);"Fear not, nor grieve! But receive the good news of Paradise which you have been promised! We have been your friends in the life of this world and are (so) in the Hereafter. Therein you shall have what your souls desire, and therein you shall have what you ask for. Entertainment from, the Oft-Forgiving, Most Merciful." (41;30-32)
According to an authentic Hadith narrated from Al-Bara' bin Azib, the angels say to the believer's soul (at the time of death);
"Come out, O good soul in a good body, as you were dwelling in it. Come out to rest and pleasant fragrances and a Lord Who is not angry."
Other scholars said that the Ayah;
يَوْمَ يَرَوْنَ الْمَلَيِكَةَ لَا بُشْرَى
(On the Day they will see the angels -- no good news),
refers to the Day of Resurrection.
This was the view of Mujahid, Ad-Dahhak and others.
But there is no contradiction between these two views, because on both of these days -- the day of death and the Day of Resurrection -- the angels will appear to the believers and disbelievers, and they will give glad tidings of divine mercy and pleasure to the believers, while they will give the disbelievers news that will bring regret and sorrow, so there will be no glad tidings for the evildoers and criminals on that Day.
وَيَقُولُونَ حِجْرًا مَّحْجُورًا
And they (angels) will say;"Hijran Mahjura."
The angels will say to the disbelievers;`success is forbidden to you this day.'
The basic meaning of Al-Hijr is preventing or prohibition, hence the word is used in the phrase "Hajara Al-Qadi `Ala Fulan" (or, "The judge prohibited so and so.") when he forbids him to dispose of his wealth in cases of bankruptcy, folly, being underage, etc.
The name of Al-Hijr (the low semicircular wall near the Ka`bah) is also derived from this root, because it prevents people from Tawaf inside it, since they have to go behind it.
The mind is also called Al-Hijr, because it prevents a person from indulging in things that do not befit him.
In conclusion, the pronoun in the phrase
وَيَقُولُونَ
(And they will say),
refers to the angels.
This was the view of Mujahid, Ikrimah, Al-Hasan, Ad-Dahhak, Qatadah, Atiyyah Al-`Awfi, Ata' Al-Khurasani, Khusayf and others;
it was also the view favored by Ibn Jarir.
Ibn Jarir recorded that Ibn Jurayj said that,
this referred to the words of the idolators.
يَوْمَ يَرَوْنَ الْمَلَيِكَةَ
On the Day they will see the angels,
means, they will seek refuge from the angels.
This is because when disaster and hardship struck, the Arabs would say;
حِجْرًا مَّحْجُورًا
(Hijran Mahjura).
Although there is a point to what Ibn Jurayj said, from the context it is unlikely that this is what was meant, and the majority of scholars said something different
