قَوْلُهُ تَعَالَى: {وَأَنْذِرْهُمْ يَوْمَ الْحَسْرَةِ} [مريم: 39]
Messenger of Allah ﷺ said, "On the Day of Resurrection Death will be brought forward in the shape of a black and white ram. Then a call maker will call, 'O people of Paradise!' Thereupon they will stretch their necks and look carefully. The caller will say, 'Do you know this?' They will say, 'Yes, this is Death.' By then all of them will have seen it. Then it will be announced again, 'O people of Hell !' They will stretch their necks and look carefully. The caller will say, 'Do you know this?' They will say, 'Yes, this is Death.' And by then all of them will have seen it. Then it (that ram) will be slaughtered and the caller will say, 'O people of Paradise! Eternity for you and no death O people of Hell! Eternity for you and no death."' Then the Prophet, recited:-- 'And warn them of the Day of distress when the case has been decided, while (now) they are in a state of carelessness (i.e. the people of the world) and they do not believe.' (19.39) (Using translation from Bukhārī 4730)
قَالَ رَسُولُ اللهِ ﷺ إِذَا دَخَلَ أَهْلُ النَّارِ النَّارَ وَأُدْخِلَ أَهْلُ الْجَنَّةِ الْجَنَّةَ يُجَاءُ بِالْمَوْتِ كَأَنَّهُ كَبْشٌ أَمْلَحُ فَيُنَادِي مُنَادٍ يَا أَهْلَ الْجَنَّةِ تَعْرِفُونَ هَذَا؟ قَالَ فَيَشْرَئِبُّونَ وَيَنْظُرُونَ وَكُلٌّ قَدْ رَأَوْهُ فَيَقُولُونَ نَعَمْ هَذَا الْمَوْتُ ثُمَّ يُنَادِي يَا أَهْلَ النَّارِ تَعْرِفُونَ هَذَا؟ فَيَشْرَئِبُّونَ وَيَنْظُرُونَ وَكُلُّهُمْ قَدْ رَأَوْهُ فَيَقُولُونَ نَعَمْ هَذَا الْمَوْتُ فَيُؤْخَذُ فَيُذْبَحُ ثُمَّ يُنَادِي يَا أَهْلَ الْجَنَّةِ خُلُودٌ وَلَا مَوْتَ وَيَا أَهْلَ النَّارِ خُلُودٌ وَلَا مَوْتَ فَذَلِكَ قَوْلُهُ {وَأَنْذِرْهُمْ يَوْمَ الْحَسْرَةِ إِذْ قُضِيَ الْأَمْرُ وَهُمْ فِي غَفْلَةٍ} [مريم 39] قَالَ أَهْلُ الدُّنْيَا فِي غَفْلَةٍ
