ذِكْرُ الْبَيَانِ بِأَنَّ سَعْدَ بْنَ مُعَاذٍ فَرَّجَ اللَّهُ عَنْهُ عَمَّا شَدَّدَ عَلَيْهِ مِنْ عَذَابِ الْقَبْرِ بِدُعَاءِ الْمُصْطَفَى ﷺ

[Machine] The Prophet ﷺ entered Saad ibn Muadh's grave and remained inside for a while. When he came out, they said to him, "O Messenger of Allah, why were you detained?" He replied, "I embraced Saad in the grave for a moment, and I sought Allah's help in releasing him, so He did."  

ابن حبّان:٧٠٣٤ – أَخْبَرَنَا الْحَسَنُ بْنُ سُفْيَانَ حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ نُمَيْرٍ حَدَّثَنَا ابْنُ فُضَيْلٍ عَنْ عَطَاءِ بْنِ السَّائِبِ عَنْ مُجَاهِدٍ عَنِ ابْنِ عُمَرَ قَالَ

دَخَلَ رَسُولُ اللَّهِ ﷺ قَبْرَهُ يَعْنِي سَعْدَ بْنَ مُعَاذٍ فَاحْتَبَسَ فَلَمَّا خَرَجَ قِيلَ يَا رَسُولَ اللَّهِ مَا حَبَسَكَ؟ قَالَ «ضُمَّ سَعْدٌ فِي الْقَبْرِ ضَمَّةً فَدَعَوْتُ اللَّهَ فَكَشَفَ عَنْهُ»

[Machine] Shook by the love for meeting Allah, the Throne implies the bed. He said, "And his parents were raised onto the Throne. Its wood was decayed." He said, "And the Messenger of Allah ﷺ entered his grave and it became narrow. When he came out, it was said, 'O Messenger of Allah, what confined you?' He said, 'Sa'd was pressed into the grave as a confinement, so I supplicated to Allah to release him.'"  

الحاكم:٤٩٢٤ – أَخْبَرَنِي عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ مُوسَى ثنا إِسْمَاعِيلُ بْنُ قُتَيْبَةَ ثنا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ثنا ابْنُ فُضَيْلٍ عَنْ عَطَاءِ بْنِ السَّائِبِ عَنْ مُجَاهِدٍ عَنِ ابْنِ عُمَرَ قَالَ

اهْتَزَّ لِحُبِّ لِقَاءِ اللَّهِ الْعَرْشُ يَعْنِي السَّرِيرَ قَالَ وَرَفَعَ أَبَوَيْهِ عَلَى الْعَرْشِ تَفَسَّخَتْ أَعْوَادُهُ قَالَ وَدَخَلَ رَسُولُ اللَّهِ ﷺ فِي قَبْرِهِ فَاحْتُبِسَ فَلَمَّا خَرَجَ قِيلَ يَا رَسُولَ اللَّهِ مَا حَبَسَكَ؟ قَالَ «ضُمَّ سَعْدٌ فِي الْقَبْرِ ضَمَّةً فَدَعَوْتُ اللَّهَ أَنْ يَكْشِفَ عَنْهُ»
