Shama-il Tirmidhi Chapter 44, Hadith Number 1 (305).

‘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”.

Commentary
This was due to the total humbleness of Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam. Some mashaa-ikh have written that this state of Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam occurred when both the jalaali and jamaali attribute of Allah appeared together. None can control the jalaali attributes. Certainly, when the jamaali attributes appeared, at that time a sort of happiness and contentment became apparent. Through the tufayl (mediation/means) of Sayyidina Rasulullah Sallallahu ‘Alayhi Wasallam the mashaa-ikh of suluk also experience these two conditions.
