Rumaitha said:

"I heard Allah’s Messenger (ﷺ)- and if I wished to kiss the seal between his shoulders, I would do so because of his nearness— say to Sa'd ibn Mu'adh on the day he died: “The Throne of the All-Merciful was shaken on his account!”

حَدَّثَنَا أَبُو مُصْعَبٍ الْمَديَنِيُّ، قَالَ‏:‏ حَدَّثَنَا يُوسُفُ بْنُ الْمَاجِشُونِ، عَنْ أَبِيهِ، عَنْ عَاصِمِ بْنِ عُمَرَ بْنِ قَتَادَةَ، عَنْ جَدَّتِهِ رُمَيْثَةَ، قَالَتْ‏:‏ سَمِعْتُ رَسُولَ اللهِ صلى الله عليه وسلم، وَلَوْ أَشَاءُ أَنْ أُقَبِّلَ الْخَاتَمَ الَّذِي بَيْنَ كَتِفَيْهِ مِنْ قُرْبِهِ لَفَعَلْتُ، يَقُولُ لِسَعْدِ بْنِ مُعَاذٍ يَوْمَ مَاتَ‏:‏ اهْتَزَّ لَهُ عَرْشُ الرَّحْمَنِ‏.‏
