IBNHIBBAN 665:
from Muṭarrif b. ʿAbdullāh b. al-Shikhhīr from his father —
[Machine] "I entered the mosque and found the Prophet ﷺ standing and praying. There was a buzzing sound coming from his chest, like the sound of a boiling pot."

عن مطرف بن عبد الله بن الشخهير عن أبيه —
«دَخَلْتُ عَلَى النَّبِيِّ ﷺ الْمَسْجِدَ وَهُوَ قَائِمٌ يُصَلِّي وَبِصَدْرِهِ أَزِيزٌ كَأَزِيزِ الْمِرْجَلِ»
