Ash-Shama'il Al-Muhammadiyah, Book 45, Hadith 322 (In-Book) ⓘ
'Abdullah bin Shikh-kheer Radiyallahu 'Anhu says: "I attended the noble assembly of Rasulullah Sallallahu 'Alayhi Wasallam. He was performing salaah. Because of his crying, such sound emmitted from his chest, like that of a boiling pot".
حَدَّثَنَا سُوَيْدُ بْنُ نَصْرٍ، قَالَ: حَدَّثَنَا عَبْدُ اللهِ بْنُ الْمُبَارِكِ، عَنْ حَمَّادِ بْنِ سَلَمَةَ، عَنْ ثَابِتٍ، عَنْ مُطَرِّفٍ وَهُوَ ابْنُ عَبْدِ اللهِ بْنِ الشِّخِّيرِ، عَنْ أَبِيهِ، قَالَ: أَتَيْتُ رَسُولَ اللهِ صلى الله عليه وسلم وَهُوَ يُصَلِّي، وَلِجَوْفِهِ أَزِيزٌ كَأَزِيزِ الْمِرْجَلِ مِنَ الْبُكَاءِ.
