Messenger of Allah ﷺ was given a silken garment, and its beauty and delicacy astonished the people. On that, Messenger of Allah ﷺ said, "No doubt, the handkerchiefs of Saʿd bin Muʿadh in Paradise are better than this." (Using translation from Bukhārī 3249)   

سَمِعتُ الْبَرَاءَ يَقُولُ أُتِيَ رَسُولُ اللهِ ﷺ بِثَوْبِ حَرِيرٍ فَجَعَلُوا يَعْجَبُونَ مِنْ حُسْنِهِ وَلِينِهِ فَقَالَ رَسُولُ اللهِ ﷺ «لَمَنْادِيلُ سَعْدٍ فِي الْجَنَّةِ خَيْرٌ مِنْ هَذَا»  

The people of (Banu) Quraiza agreed to accept the verdict of Saʿd bin Muʿadh. So the Prophet ﷺ sent for Saʿd, and the latter came (riding) a donkey and when he approached the Mosque, the Prophet ﷺ said to the Ansar, "Get up for your chief or for the best among you." Then the Prophet ﷺ said (to Saʿd)." These (i.e. Banu Quraiza) have agreed to accept your verdict." Saʿd said, "Kill their (men) warriors and take their offspring as captives, "On that the Prophet ﷺ said, "You have judged according to Allah's Judgment," or said, "according to the King's judgment." (Using translation from Bukhārī 4121)   

سَمِعْتُ أَبَا سَعِيدٍ الْخُدْرِيَّ يَقُولُ نَزَلَ أَهْلُ قُرَيْظَةَ عَلَى حَكَمِ سَعْدِ بْنِ مُعَاذٍ فَأَرْسَلَ رَسُولُ اللهِ ﷺ إِلَى سَعْدِ بْنِ مُعَاذٍ فَأَتَاهُ عَلَى حِمَارٍ فَلَمَّا دَنَا قَرِيبًا مِنَ الْمَسْجِدِ قَالَ رَسُولُ اللهِ ﷺ لِلْأَنْصَارِ «قُومُوا إِلَى سَيِّدِكُمْ» ثُمَّ قَالَ «إِنَّ هَؤُلَاءِ نَزَلُوا عَلَى حُكْمِكَ» قَالَ «تُقَتَّلُ مُقَاتِلَتُهُمْ وَتُسْبَى ذُرِّيَّتُهُمْ» قَالَ النَّبِيُّ ﷺ «قَضَيْتَ بِحُكْمِ اللهِ» وَرُبَّمَا قَالَ «قَضَيْتَ بِحُكْمِ الْمَلِكِ»  

[Machine] "And their wealth is distributed, so he mentioned that to the Prophet ﷺ who said, 'Indeed, Allah has ruled upon them with His ruling that is above His seven heavens.'"  

وَأَنْ تُقَسَّمَ أَمْوَالُهُمْ فَذَكَرَ ذَلِكَ لِلنَّبِيِّ ﷺ فَقَالَ «لَقَدْ حَكَمَ فِيهِمْ حُكْمَ اللهِ الَّذِي حَكَمَ بِهِ فَوْقَ سَبْعِ سَمَوَاتِهِ»  

[Machine] The Messenger of Allah ﷺ said to Sa'd as he was being buried, "Indeed, the righteous servant has caused the Throne to move for him, and the gates of the heavens have been opened for him."  

قَالَ رَسُولُ اللهِ ﷺ لِسَعْدٍ وَهُوَ يُدْفَنُ «إِنَّ هَذَا الْعَبْدَ الصَّالِحَ تَحَرَّكَ لَهُ الْعَرْشُ وَفُتِّحَتْ لَهُ أَبْوَابُ السَّمَاءِ»  

"The Messenger of Allah said: 'The Throne of The Most Merciful trembled upon the death of Sa'd bin Mu'adh.'" (Using translation from Ibn Mājah 158)   

عَنِ النَّبِيِّ ﷺ قَالَ «اهْتَزَّ الْعَرْشُ لِمَوْتِ سَعْدِ بْنِ مُعَاذٍ»
